DOW-UAP-D017, UAP Reported at Sandia Base, 1948-1950

▮ AI SYNOPSIS · Sonnet 4.6

DOW-UAP-D017 is a 116-page compilation from the Armed Forces Special Weapons Program (AFSWP) and the U.S. Air Force covering 209 reported UAP sightings at and around Sandia Base, Albuquerque, New Mexico, between 1948 and 1950. Observed phenomena included "green fireballs," luminous orbs, and disc-shaped objects described as maneuvering, disappearing, or exploding. The file includes correspondence between military officers, OSI agents, and civilian scientists — notably meteoriticist Dr. Lincoln LaPaz and physicist Dr. W.D. Crozier of New Mexico School of Mines — who conducted field investigations following specific incidents, including a fireball event on July 24, 1949, near Socorro.

The scientific content is notable: airborne particle collections taken after fireball events yielded copper-bearing particles of anomalous size and composition, which investigators acknowledged were inconsistent with known meteoritic material. LaPaz explicitly stated that copper is among the rarest elements in meteorites and that its presence, if confirmed as originating from the fireballs, would rule out a conventional meteoric explanation. Results were characterized as inconclusive. Some pages relate to unconnected base security matters, suggesting the file is an administrative compilation rather than a single continuous investigation. The green fireball sightings documented here directly fed into the formation of Project Grudge.

▮ TOP WORDS IN THIS DOCUMENT

This file contains 116 pages of documentation from the Armed Forces Special Weapons Program (AFSWP) – the direct, post-World War II successor to the Manhattan Project – and from the U.S. Air Force – relating to a series of sightings and investigations in Sandia, New Mexico, from 1948-1950. This file contains 209 sightings of “green orbs,” “discs,” and “fireballs” reported near the military base. Witnesses reported unidentified anomalous phenomena (UAP) maneuvering, flying out of sight, disappearing, or exploding. The documents also include the results of contemporary investigations into residual copper powder found in some areas where sightings were reported. A few of these investigations became the basis for Project Grudge, which collected reports of unidentified flying objects from various other military installations – also included in this collection.

M. Dear Lincoln: I am inclosing two copies of the report you asked for, and hope that they serve their purpose. We have made a preliminary examination of the eighteen collections taken at nine locations on my. Mondey-Tuesday trip. There was a large number of copper-bearing particles on one collection (R-104L) talen on Highwey 84, seventeen miles north of Highway 66, and scattered occas- ional particles throughout the series. The collection taken at the sane location immediately following R-104I shows practically no copper. A large part of the R-104L is of a granular material unfamiliar to us, and the copper indications originate principally in what are apparently aggregations of finely (one-mieron) granuler material of overall sizes ever, appear to be solid and opaque. The passage of two automobiles while to see how they might have been a source of copper, however, unless it was a question of stirring up some from dust on the pavement. We intend to do some further chemical work with these collections, but I doubt if much new relevant information will be obtained. My tentative conclusion is that no widespread significant dispersion of copper-bearing perticles was present in the atmosphere in the resion covered at the time the collections were made. No definite statement is possible about the one heavy copper collections it should be presumed to be of local origin until some evidence to the contrary is found. The route of the collecting triy Ineluded Pastura, Sente Rosa, june- tion of Routes 66 and 84, and las Vegas on Monday afternoon.

SECRET R/D-tw 8-10-49 AN ATTEMPE DO COLLECT AIRBORNE PARTICLES ASSOGIATED WITH THE FIREBALI OF JULY 24, 1949 By * D. Crozier and Ben K, Seely NEM MEXICO SCHOOL OF MINES METHOD A fireball was reported to have passed over the general neighborhood of SocorrO, New Mexico, at 8:26 p."+, July 24, 1949, Impactment equipment, developed in connection with the aerosol research projeet of the New Mexico School of Mines, was available, and it was decided to make systematic collections of airborne mater- -lel in the hope of obtaining material that could be associated with the fireball. For the present report it is sufficient to state that the equipment processed air at the rate of about 34 liters per minute, the particles being separated from the air by impactment against an adhesive-coated plate in an air jet. Approximately ninety per cent of airborne particles with dismeters greater than one micron are collected. The adhesive used on the collecting plates (microscope slides) was a glycerin- gelatin mixture with an addition of rubeanie acid (dithiooxemide.) This reagent was used to enable identification of copper or copper compounds; it also enables identification of nickel and cobalt. Alter making the collections, the slides were covered with a Saran film, after which they were exposed to strong ammonia vapor for fifteen minutes to effect partial solution of any copper or copper oxide perti- eles. RESULTS The first collection was made at 10:00 a.m., July 25, about thirteen and one- half hours after the fireball was seen. The air was taken about twelve feet above ground level, on the campus of the School of Mines. The first run was for three min- utes, processing about 102 liters of air. Several large particles were found in it that gave positive copper tests. In at least one of these the copper reaction was seen before the amonia treatment, indicating the presence of at least a trace of a soluble copper compound. The sizes of particles seen in the first collections ranged up to over one hundred microns in the largest dimensions the largest particles gave the impression of being fragnents of a somewhat fibrous material, with the smaller NND 58378

SECRE Page 2 dimension of the order of twenty or thirty mierons. There were no small partioles, that 1s, no partieles with a maximum dimension below 15 microns. . Following the first collection, additional collections were made, under sini- lar conditions, over a period of eight days. The accompanying table summarises the conditions and copper counts for all these collections, ineluding the first one described above. A number of the runs were for periods longer than three minutes, but the counts have, in these cases, been reduced to the three minute equivalent. one collection showing several large copper indications, taken July 25, is omitted from the table because it was damaged in course of a test for radioativity by exposure of a nuclear track plate (with negative resulto) and a definite count cold not be made. The counts are exhibited in three size classifications, and attention is directed to the fact that particles in the smellest size group (1 to 15 microns) are practically absent from the early collections, while in the later collections, particles in the largest (30 microns) and middle (15 to 30 microns) groups have becone quite scarce. At the same tine, the counts have becone quite large in the siallest size group. SIGNITICANCE OF RESULTS If it were possible to say that particles giving a copper test are generally very rare in collections near ground level in this locality, the above facts to uld bo highly significant. It happens, however, that collections have been made at Socorro over only a short period, and not much attention has been given to identi- fication of copper compounds. However, after the copper indications had been found in the prosent series of collections, some collections were found on file that had been made on plain glyeerin-selatin on July 14, 1949. These were covered with the Saran film and rubeanie asid and armonia were applied by diffusion through the tilm. A few copper indications were found, almost all the particles being in the 30 mieron size group. Some other collections were made early in July that will be examined for copper when they are freed from other tests. In addition, occasional collections will be examined for copper in the future, and it may be possible eventually to add something to the information now presented. CONCLUSIONS REGARDING COPPER In view of the above facts, it seems very hazardous to drew any definite con- clusion associating the copper-bearing partioles collected with the fireball of July There still is, however, a residum of possiblity of such associations men 1t is considered thet particles of the smallest size group did not appear in large numbers until some 35 hours alter the passage of the fireball.

SECRET Page 3 Attention is called particularly to the large number of amall particles in one of the 145-1/2-hour collections. The actual number in the collection was 140, for the five-minute run. Most al these were in the size range of two to five mierons, and the principal difficulty in associating them with the fireball is that a five- micron particle cannot fall nuch nore than 10,000 feet in 145.5 hours. These parti- clos could have come down fron a greater height only if some downward motion had taken place in part of the air involved. It should be mentioned that collections were taken during the afternoon of July 27, at several points south and east of Socorro, the farthest being neer Binghan. These collections contained particles giving copper indications, the partiales being in the sane range of sizes as those collected in Socorro at about the same time. It is perhaps noteworthy that the copper-bearing particles in all these collec- tions were of opaque material, lost of the copper minerals that have previously con come to our attention in collections from the air have been colored material, blue, green, red, or yellow. COBALT AND NIOKEL TESTS In the 2100 p»i. collection of July 26, three quite remariable particles were found that gave very strong cobalt indications. The particles were apparently per- fect spheres (at least they were perfectly circular in cross section), twelve mic- rons in diameter. The reaction with rubeanie acid, after ammonia treatment, pro- duced a dense yellow-tan halo, sixty microns in dianeter. The color was not quite so clear es with pure cobalt: the appearance susgesting a high-cobalt composition with some metal present. Such particles are quite unique in the experience of the present., If these particles were of neteoritic origin they could, in the absence of vertical air novement, have fallen a distance of the order of 20,000 feet in an interval of 41,5 hours. Two particles giving nickel indications were found, This is quite normal, how- ever. If anything, the number is smaller than might have been expected in material of surface origin. The collections were not given acid treatment: additional nickel indications might have been found if this had been done. AL SUGGESIION While the results of the present investigation should be regarded as negative or inconclusive, it is desired to call attention to the fact that a means is at hand that should make possible a definite demonstration of the presence or absence of cop- per particles associated with events of the July 24th type. article collection equipment, operating on the same principle as that used il che present investigation, and designed for airplene installation, is on hand an its successful operation has been demonstrated in numeroils slights.

ECRET page 4 could easily be made for quickly mounting this equipment in an airplane espable of ascending above the 40,000-foot level, which could take off soon after an event of the July 24th kind, and fly a pattern that would include with reasonable certeinty some of the material originating at the meteor trajectory. A quick approximate determination of the trajectory would be required, of course, and if winds aloft were of considerable strength it would be necessary to make due allowance for them in planning the flight. NORS ADDED ON AUGUST 20, 19493 As this report was being finished, an attempt was nade at an airplane collection following the event of August 6. The collecting equipment was installed in a B-25 from Kirtied field and on the afternoon of August 8, a flight was made which it was hoped might intercept son of the meteoritic material. An Interval of 41 hours had passed before the take-off, and the maximum alti- tude reached was 23,000 feet. A rough attenpt was made to include air that was under the trajectory, but distances of several hundred miles were involved. A few copper indications were obtained, but they seemed definitely to be associated with material of surface origin. No nickel or cobalt indications were found. An elabor- ate study, which may require more upper air data than is available, should be made before it is decided whether or not the flight did actually include air that should have borne particles fron the meteor trajectory.

• SECRET Anguat 17, 1949 TO: Colonel Doyle Rees FROM: Lincoln LaPan SUBTIOT: Anomalous Luminous Phenonena. Sixth Report (attempts to colleet volatill- zation products from green fireballs) In an earlier report it has been pointed out that in spite of air and ground searche in early February along the well deterined earth-trace of the green fireball of 1949, January 30th no fragments of this fireball were recovered. There remained the possibility that this fireball had been so completely volatilized during flight that only fine dust from it filtered down thru the atmosphere. Since, foz several reasons, it seemed more probable that such dust would consist chiefly of copper or a copper alloy rather than of the ferro- magnetie substances found for ordinary neteorites, the methods habitually employed by meteoriticists for the collection of "coania dust" (separation of the dust from the air by use of electromagnets or permanent magnets) voulá not be appropri- ate for use in connection with the green fireballs. It was therefore deeided to enlist the aid of Dr. W121iam Crozier, who wes knownto have developed a novel impaotnent dust collector for use on the Aerosol Project of the New Mexico School of Mines. (The writer had been closely associated, in 1943-44, with Dr. Crozier at New Mexico Proving Grounds while working on saboted and proximity fused shells and knew that he had satisfactory clemrance.) Dr. Crozier not only agreed to partici- pate in a ground-level search for dust possibly put down by the fireball of Jan- uary ,30th, but made the valuable suggestion that dust collections be made on plene flights routed back and forth at high altitudes through the air beneath green fireball paths as soon as possible after fireball fall. In this manner contani- nation of the dust collections by terrestrial particles would be reduced to a minimui. No immediate application was made of Dr. Grozier's dust colleetion techniques, in part because of the writer's return to full time ncadenie work at the UNM on Februry 8th and in part because of Dr. Crozier's other zesearch activities and the interruptions in Research and Development Division work inci- dent to the A.5.C.'s taking over the Albuquerque quarters of the Division. When it was determined that the green tireball of July 24th had descended in the immediate violnity of Socorro, it wes decided to ask Dr. Crozier to attempt collections even though he and his staff were then engaged in the final stages of moving from Albuquerque to their new quarters on the Campus of the New Mexico School of Minos. A long distance call to De, Grozier on July 86th brought the welcome news that he had been alerted by an appeal for observations issued by the Institute of Meteorities on the evening of July 84th and had already made dust collections on the campus at Socorro on the morning of July 25, These collections, to Dr. Crozier's evident surprise, were found to contain not only the firet copper particles he had found.in air dust collections but these particles were of unusually large size - up to 100 microns in maximun dimensions. On receipt of this exciting information, a party was dispatched from 17th Distriet 0.S.I. Hags. to confer with Dr. Crozier and to make a field search for the fireball of July 24th, This party consisted of Major Charles I, Phillips (courteously made available for the trip by Colonel Harold A Gunn, C.0, of Kirtland Pield) Mr. Paul Taft of the U.S, Weather Bureau in Albuquerque, S/A Jack Boling and the undersigned. A conference with Dr. Grozier and Mr. Ben Seely was held on the School of Mines campus in Socorro between SECRET NND 58378

━ PAGE 11 ━

- 2 - SECRE 10:00 - 18:00 A.M. on July 26th. At this conference it became apparent that Dr. Crozier was inolined to attribute the unusually large copper fragments collected on July 25 at 10:00 A.M. ("which because of their size could not have been blow very far by surface winds") to particles blown off the roof or out of the gutters of the Assaying Building on the Campus. In answer to a question from the writer, Dr. Crozier replied that he would consider this possibility ruled out if copper particles showed up in collections made in the open country at considerable distances from the Campus. It was therefore recommended that such collections be made and Dr. Crozier and Jr. Seely rigged up a storage battery combination and amall D.C. motor driven impatient collector which were loaded into the O.S.I. staff ear and driven out through San Antonio, Carthage, and Binghem, New Mexico (this route passing, in Mr, Taft's opinion, through the region where particles from the fireball of July 24th would most probably have been carried by the very light winds prevailing in the region since the inci- dent.) Tour of the collections made on this trip were examined on the evening of July 26th by It. Ben Seely and all were found to contain copper particles indistinguishable from those collected in Socorro at about the sane time. (3) Full details on the methods of collection employed by Dr. Crozier and Mr. Seely and on later examinations of the dust particles collected after the greon fireballs of both July 24th and August 6th are given in Dr. Crozier's report (R/D - tw, 8-10-49) copies of which are hereto appended. De, Crozier's tentative conclusion from study of the collections made, not only in comection with the incident of July 24th, but also that of August oth, is that "the resulte of the present investigation should be regarded as negative or inconclusive." From analysis of his report (R/D - tw, 8-10-49) and from several phone conver- sations with Dr. Crozier, it is the writers belief that Dr. Crozier was led to the above conclusion by the following facts listed below in decreasing order of importance, and accompanied by eritical comments: (3.1) The discovery by tests made on or about August 1 of " a few copper indications" in dust colleeted at Socorro on July 14, 1949, 1.0. ten days before the green fireball ineident of July 24th. (Dr. Crozier has informed the writer that the collection of July l4th was carefully wrapped up and could not have become contaminated by copped dust which blew in through the open win- dows of the R.D. &D. Building at Socorro after the inoident of July 2th. How- ever, there remains the possibility that an unotserved or unreported green fire- ball oceurring in the Socorro neighborhood shortly before July 14th put down the copper dust found in the July 14th collection. To one familiar with the almost uninhabited country around Socorro end the fact that green fireballs as bright as the half moon occurring at times as favorable for observation as 7:30 - 8:30 Pol, have gone almost unreported, it seema quite likely that a green fireball that fell after midnight or during the daytime or while most of the sky was overcast night go entirely unreported.) The discrepangy between the computed and observed rates of descent of very fine copper particles. (As Dr. Crozier notes, such diserepan- cies are understendable "If some downward motion had taken place in part of the air involved." Precisely such downward motion oceurred in the air near the real paths of the fireballs of July 24th and Angust 6th for these falls were nearly vertical. Furthermore the best observations of the endpoints of these fireballs place that of July 24th at a hight of 10-12 miles and that of August 6th at 5-6 miles. The downward direeted ballistic head wave therefore could very easily have carried Dr. Crozierts 145 hour particlos to within 10,000 feet of the earth at NND 58378

━ PAGE 12 ━

- 3 - SECRET the time of fall. Since we cannot assune complete stagnation of the air masses in the Socorro neighborhood for 145 hours, it must be supposed that such air motions as occurred were approximately compensating and resulted in the return of Dr. Crozier's tiny "five-nieron particles" to the Socorro neighborhood in approximately 145 hours. Only a detailed study of air mass motions for the time interval involved can settle this point.) (3.3) The long continued appearance of copper particles (however, as Dr. Crozier emphasizes, smaller and smaller in size) in the Socorro collections. (Precisely such a decrease in particle size has repeatedly been observed in connection with dust collections believed to be of meteoritic origin and is attrib- uted to the slower and slower rate of descent of the particles as their average size decreases. Thus, L, Rudaux's results strongly indicate that partiales fron the Giacobinid shower of 1933, October 9, filtered down in smaller and smaller sizes for 100 hours or more. Furthermore, for the green fireballs of July 24th and August 6th, the nearly vertical real paths extended from altitudes of 100 miles or more down almost to ground level and therefore optimum conditions for long continued infall of dust particles were approached in these falls.) (3.4) Jailure of the airplane collection of Augut 8th to deteet air- borne copper particles definitely not of terrestrial origin. (However, airplane collections were all made at great distances (hundreds of miles) from the Vaughn region in which the fireball of August 6th fell; and, as Dr, Crozier points out, at the moment it can not be determined "whether or not the flight did actually include air that should have borne partieles fran meteor trajeetory." In this connection the results alluded to in paragraph 4, below, may be of considerable significance.) (4) At the time the airplane collection of August 8th was planned the writer recormended not only that the flight traverse the area from Vaughn northward to Raton and then Ni-ward into the Durango, Colorado region (a recommendation based on advice received from Mr. Paul Taft of the U.S, Weather Bureau) but also that simultaneously a ground search with the portable impactment dust collecting equip- ment rigged up on July 27th be run from Vaughn through Pastura to Santa Rosa. The latter part of this recommendation was followed by Dr. Crosier who reported on the results obtained in his letter to me under date of August 10, copies of which are hereto attached. Dr. Crozierts letter makes clear that ground collec- tions in the sublinal regions of the fireballs of both August 6th and July 84th resulted in the detection of unusual aggregations of copper particles, Apparently the copper particle aggregate obtained in collection R - 104L, within the subrinal region of the August 6th fall was the only such aggregate found in Dr. Crozier's lenghty ground search of August 8-9. It seema perticularly significent to the writer that Dr. Crozier suspects that the copper dust found in this particular collection R-1041, may have been stirred up fron the pavement on Highwey 84 ---- a likely catchient surface for dust put down by the green fireball of. August 6th, in view of the information given me by Mr. Taft in regard to the wind direction prevailing during the hours immediately following this ineident. (5)8 In spite of the eritical coments made in paragraphs 3 and 4 above, the writer has no quarrel with Dr. Crozier's conclusion that the results so far obtained in the investigation of volatilization produeta possible put down by stress most emphatically that if future more detailed work shows that the numer- ous copper particles found by Dr. Crozier and Mr. Seely are indeed floating down SECRE MOLT NND 58378

Merrill, Memoire National Academy of Science, vol. 14 (1925), Table facing p. 27; and Harrison. Brown, Journal of Geology, vol. 56 (Merch 1948,) Table 1, P• 87•. fact, I know of no case in which even the tiniest particle of copper has been reported in a dust collection supposedly of meteoritie origin. In view of present concern in regard to the true nature of the green fireballs, nothing could exeeed in importance attainment of a definite conclusion in regard to the origin of the copper particlos detected in the eubfinal regions of the fireballs of July 24th and August 6th. (6) The writer therefore wishes to make the following recommendations: (6.1) That arrangements be made for dust collections on airplane flights at altitudes of 40,000 ft. or more through the region of the atmosphere lying beneath the real paths of green fireballs as soon as possible after the oceurrence of such fireball incidents. Such errangements presuppose a well coordinated observing network pernitting the speediest possible determination of the location of the real patha in the atmosphere. (Dr, Crozier and Mr. Seely have both agreed to cooperate in earrying out dust collection at the highest altitudes attainable. In Dr. Crozier's opinion, a B-36 or B-50 should be made available far such work. ) (6.2) That ground-level dust collections be made along the well deter- mined earth-trace of the green fireball of January 30th, using the portable impact- ment equipment already rigged up by Dr. Crozier and Mr. Seely and used in the ground searches of July 27th and August 8-9th. If copper particles can be recovered along this earth-trace but do not appear in collections made 50 miles or so ewey fron the trace, the result would be of much significance if not indeed decisivo.

CON DEPARTMENT OF THE AIR FORCE HEADQUARTERS UNITED STATES AIR FORCE WASHINGTON DECLASSIFIED Authority NW 01S26 THE INSPECTOR GENERAL USAF 17TH DISTRICT OFFICE OF SPECIAL INVESTIGATIONS KIRTLAND AIR FORCE BASE, NEW MEXICO DR/ms 25 May 1950 File No: (24-8)-28 SUBJECT: Summary of Observations of Aerial Phenomena in the New Mexico Area, December 1948 - Hay 1950 TO : Brigadier General Joseph F. Carroll Director of Special Investigations Headquarters USAF Washington 25, D. C. In a liaison meeting with other military ánd government intel- ligence and investigative agencies in December 1948, it was determined that the frequency of unexplained aerial phenomena in the New Mexico area was such that an organized plan of reporting these observations should be undertaken. The organization and physical location of units of this Dis- trict were most suitable for collecting these data, therefore, since December 1948, this District has assumed the responsibility for collect- ing and reporting basic information with respect to aerial phenomena occurring in this general area. These reports have been distributed to the Air Materiel Command, USAF, in accordance with Air Intelligence Requirements No. 4, and to other interested military and government agencies, 2. There is attached, as a part of this summary, a compilation of aerial phenomena sightings that have occurred mostly in the New Mexico area and have been reported by this District Office subsequent to December 1948. This compilation of sightings is not a complete record of all reported observations, but includes only those in which sufficient information was available to justify their inclusion. The observers of these phenomena include scientists, Special Agents of the Office of Special Investigations (IG) USAF, airline pilots, military pilots, Los Alamos Security Inspectors, military personnel, and many other persons of various occupations whose reliability is not questioned. This com- pilation sets forth the most important characteristics with respect to each observation and evaluates each sighting into one of three classifi- cations, (1) green fireball phenomenon, (2) disc or variation, and (3) probably meteoric. 3. There is also attached an analysis of the green fireball occurrences in this area made by Dr. Lincoln LaPaz. Dr. LaPaz is the COT NW 91526

€O TAI File No: (24-8)-28 Subj: Summary of Observations of Aerial Phenomena in the New Mexico Area, December 1948 - Way 1950 25 May 1950 Director of the Institute of Meteoritics and Head of the Department of Mathematics and Astronomy at the University of New Moxico. He was Re- search Mathematician at the New Mexico Proving Grounds under an OSRD trict in connection with the green fireball investigations. On 17 February 1949 and again on 14 October 1949, conferences were held at Los Alamos, New Mexico, for the purpose of discussing the green fireball phenomena. Representatives of the following organizations were present at these mectings: Fourth Army, Armed Forces Special Wea- pons Project, University of New Mexico, Fedoral Bureau of Investigation, U. S, Atomic Energy Comission, University of California, U. S. Air Force Scientific Advisory Board, Geophysical Research Division Air Materiol Commend USAF, and the Office of Special Investigations (IG) USAF. A logical explanation was not proffered with respect to the origin of tho green fireballs. It was, however, generally concluded that tho pheno- mena existed and that they should be studied scientifically until these occurrences have been satisfactorily explained. Further, that tho continued occurrence of unexplained phenomena of this nature in the vicinity of sensitivo installations is cause for concern. The Geophysical Rescarch Division, Air Materiol Command, Cambridge, Massachusotts, has recently let a contract to Land-Air, Inc., Holloman AFB, Alamogordo, New Mexico, for a limited scientific study of green fireballs. The results of this sciontific approach to the problem will undoubtedly be of great value in determining tho origin of these phenomena. This summary of observations of aerial phenomena has been prepared for the purpose of re-emphasizing and reiterating the fact that phenomena have continuously occurred in the New Moxico skies during the past 18 months and are continuing to occur, and, secondly, that these phenomena are occurring in the vicinity of sensitive mili- tary and government installations.

Sighting No. 175 Photograph of Unknown Aerial Phenomena taken at Datil, New Mexico by Cpl Lertis E. Stanfield, Holloman Air Force Base, New wexico on 24 and 25 Feb 1950. An analysis of the above photograph was made by Dr. Lincoln LaPaz, Head of the Institute of Meteoritics, University of New I mexico, Albuquerque, New Mexico, who reached the following con- clusions: a. The angular diameter of the perfectly round luminous object Stanfield observed was approx- imately 1/4 of a degree. b. The angular velocity of the object in the sky was greater than half a degree per minute. Dr. LaPaz stated that on the basis of the results (a) and (b) above, the object seen by Stanfield was not the moon (for the angular diameter is too small), it was not Venus or any other planet (for the angular diameter was too large), and it was not a bright fixed star slightly out of focus (for the observed rate of motion is double that due to the diurnal rotation of the earth).

THE UNIVERSITY OF NEW MEXICO ALBUQUERQUE INSTITUTE OF METEORITICS May 23, 1950 To: Lt. Colonel Doyle Rees, Commanding Officer 17th District, O. S. I. From: Lincoln LaPaz, Director Institute of Meteoritics Subject: Anomalous Luminous Phenomena (Seventh Report) 1. In the second report of this series, dated 1948, December 20, the writer listed ten significant differences between the bright green horizon- tally-moving fireballs observed in the interval 1948, Decenber 5-20, and typical meteors. These differences were the following: (1) The horizontal nature of the paths of most of the December fireballs is most unusual. Genuine meteors are rarely observed to move in horizontal paths. (2) Again the very low height of the December fireball discussed in section 2 above sets it off in sharp contrast from the genuine meteors for which heights of the order of 40 or more miles are nor- mally observed. (3) The velocity determined for the fireball of December 12 is much less than the velocities determined from typical meteors (and yet is considerably greater than the speeds of the V-2 Rockets or jet planes or of conventional flares). (4) In the case of meteorites that penetrate to as low levels as that determined for the fireball of December 12, the observed lu- minous phenomena are always accompanied by very violent noises. No noises whatever have been observed in connection with the various December fireballs so far investigated. (Note added on 1950, May 23: Possible exceptions to the noiselessness of green fireballs are the incidents of 1949, January 30, and 1949, December 4.) (5) Genuine meteors normally show remarkable variations in brightness, beginning as fine thin hair lines, which are scarcely visible to the observer, and then brightening up to flash out near the end of their paths. In the case of the December firchalls most of the observers have reported that the green balls appeared almost instantly at their full brightness. ONFI NW 91526

To: Lt. Colonel Doyle Rees - Page 2 Subj: Anomalous Luminous Phenomena (Seventh Report) May 23, 1950 (6) In the case of genuinc meteors the paths are dirocted to- ward all points of the compass with equal frequency. On the contrary in the case of the groen fireballs, plots of admissible approaca sec- tors show that there is a very pronounced tendency for the paths to come in from the north half of the sly. (7) The three groups of anomalous greenish luminous phenomena show a curious association with well known moteor showers, although none of these meteor showers normally produce extremely bright green fireballs, such as those recently observed. For example, the obser- vetion mentioned by lir. Tonig appeared neer the manimum of the Quadrantid shower of carly January, Ir. IcCullough's observation of August was near the time of the Porsid shower and the December observations all fell in the interval covered by the Geminia shower. This relationship might indicate an attempt to render the green firo- balls less conspicuous by causing them to eppear only whon there is considerable meteoric activity. (8) As noted in an carlior communiention, the remarkably vivid groen color reported for most of the December firoballs is rarely observed in the case of genine moteors. By lacoratory test this peculiar color seems to bo identical with that given off by copper salts in the blowpipe flame. If this idontification is correct, the wave longth of the radiation from the greon fireballs is noar × -5218R. (9) Tho duration estinates of botween 2 and 3 scconds reported for tho green fireballs are considerably longor than thoso (0.4 - 0.5 seconds) for the ordinary visual motors, but shortor than the duration ostimates invariably roported in the caso of a senuine moteorite fall (5 to 30 sceonds or ovon longer). (10) For nono of the groon fireballs has a train of sparles or a dust cloud boon reported. This contrasts sharply with the be- havior noted in casc of metcoric fircballs--particularly thoso that penotrate to the vory low levels whore the groon fireball of December 12 was observed. 2. In the year and a half since this list was propared, many ad- ditional observations have been mado, the total numbor of objects now accepted as belonging in the greon fireball catogory being 72. (A1- though this number constitutes nearly 50% of the incidents listod in tho accompanying Summary, it constitutes less than 5% of tho sotal number of unscreened observations roported to the writer.) Critical analysis of all green fireball reports now availablo shows that only one of the statements in the list givon in paragraph l needs to bo modirica, namely, item (1). Within the last year, a considerable number of the greon fireballs have appeared to fall vortically downward rather than CONFIDENTIAL NW 91526

To: Lt. Colonel Doyle Rees - Page 3 Subj: Anomalous Luminous Phenomena (Seventh Report) May 23, 1950 to move horizontally. However, a strictly vertical infall is also very rarely observed in the case of genuine meteor falls. 3. An analysis just completed of the time distribution of the green fireballs so far observed permits us to add an llth item to the list of differences given in paragraph l above. The graph of frequency versus local time which accompanies the present report shows that the maxinum frequency of sighting of green fireballs (occurring at approximately 2030) coincides in time with neither the frequency maximum for ordinary meteors (occurring at approximately 0300) nor the frequency maximun for meteorite falls (occurring at approximately 1600). 4. Inspection of the graph referred to in paragraph 3 also will show that most of the green fireballs have been sighted in a time inter- val extending from about 5 p.m. to 11 p.m. (MST). This concentration might be even more pronounced if it were possible to screen out of the secondary maximum, around 2 a.m. (MST), all ordinary meteors which have been mistakenly identified as green fireballs. That such misidentifica- tion has occurred is strongly suggested by the near coincidence in time of the secondary maxinum of the green fircballs and the well established carly morning maximum of the ordinary meteors. 5. Some significance may attach to the fact that the time interval alluded to in paragraph 4 extends from about 7 a.m. to 1 p.m. in the Ural region of the USSR. Since missiles moving with velocities of the order of those found for the green fireballs for which real path determinations have been possible would travel from the southern Urals to New Mexico in less than 15 minutes, a possible interpretation of the concentration of sightings referred to in paragraph 4 is that the green fireballs result from guided missiles launched from bases in the Urals in the morning hours before cloudiness due to convection or blinding afternoon dust storms can interfere with non-radar tracking, such as has been used by the Optical Trajectory Section at White Sands Proving Ground. 6. There is also a pronounced concentration of green fireball incidonts on the four days, Friday, Saturday, Sunday, Monday, almost all of the most widely observed incidents having occurrod on Saturday or Sunday• 7. It is a curious and fairly well-established fact that there has been a distinct decline in the numbor of green fireball sightings during the last two months, within which the number of so-called "fly- ing saucer" incidents in this region has attained an all-time high. Although I have recently received from Dr. Joseph Kaplan of the Scientific Advisory Board a letter containing the statement "Frankly, I don't know of any U. S. experiments that would result in the appearance of those unconventional objects, and neither does Von Karmen". I still DENTIAL NW 91526

CONI To: Lt. Colonel Doyle Rees - Page 4 Subj: Anomalous Luminous Phenomena (Seventh Report) Tay 23, 1950 consider the most probable explanation of the green fireballs to be the one given in the first of the three paragra hs below which are quoted from my letter of 1950, February 20, to Dr. P. I. Wyckoff, Chief Atmos- pheric Thysics Laboratory, Base Directorate for Geophysical Research. The last two paragraphs quoted below well summarize my recommendations concerning the green fireball problem: "As a preliminary to setting down the project recommendetions which you requested, I have very carefully reviewed all available fireball data (observers' reports, transit measurements, calculated real paths, etc.) covering incidents fron those of December 5, 1948 to the extraordinary incident of February 7, 1950, which has been under intensive investigation for the last two weeks. As a result of this comprehensive review, particularly as it relates to the in- cident of February 7, 1950, I feel compelled to write you in some- what different terms concerning my on part in the proposed fireball project than I had in mind when we last discussed this matter. brief, I have come to the conclusion thot, on the basis of the evidence now available to me, I would not be justified in recomend- ing a fireball project. In my opinion, this evidence proves conclu- sively that the fireballs reportod on fall into one of two categories: Those of the first category (the majority) are meteorite falls of musual, but certainly not of impossible, magnitude, frequency and other characteristics; those of the second category (the minority) are U. S. guided missiles undergoing tests in the neighborhoods of the sensitive installations they are designed to defend. This interpretation of the latter category is the one that I proposed in answer to a question raised by Dr. Teller at the first Los Almos conference on February 17, 1949. It was not taken seriously then and I doubt that it will be taien seriously at the present time. However, even if my interpretation of the unconventional fireballs is the correct one, it is obvious that those in position to confirm it should refuse to do so." "Only one other point need be stressed, namely, that if I am wrong in interpreting the guided missiles es of U. S. origin, then certainly intensivo, systematic investi ation of those objects should not be delaved until the terminacion of the present academic year• Recent international developments compel one to sense the imperative necessity of immediate investigation of the unconvention-. al green fireballs, in case you are in possession of information proving that they are not U. S. missiles." "If such on immediate investigation were to be underteler, I would recormend that Dr. Fred L. Thipple, of larvard College Obser- vatory, be placed in charge of the photographic plase of the inves- tigation; that Dr. Peter M. Millman, of the Dominion Observatory, be placed in charge of the spectrographic phase of the investigation; NW 91526

━ PAGE 67 ━

To: It. Colonel Doyle Rees - Page 5 Subj: Anomalous Luminous Phenomena (Seventh Report) May 23, 1950 that Dr. L. A. Manning, of Stanford, and Dr. Millman be placed in charge of the radar investigation; and, finally, that Dr. Tilliam Crozier, of the New Mexico School of Mines, be placca in charge of dust collection and identification. On the basis of many intensive field surveys, I do not anticipate that ground scarch will lead to any rocoveries, but in case such ground soarch is to be attempted, it should be carried out on the scale stressed in my conversations with you and Major Oder last month. Although the acove paragraphs were written somo months ago, the recommendations contained in them are the ones I would urge you to con- sider at the present time. In conclusion, I should like to repeat the offer made at the end of my letter of February 20 to Dr. Wyckoff, namoly to serve, if needed, as consultant on the greon fireboll projoct suggested in lajor Oder's letter to me under date of lovembor 29, 1949, with the stipulation, however, that my service be on a voluntary basis rathor than on the (40 per day contract spocified in lejor Odorts letter.

This is a comprehensive summary of all observations of unidenti- fied aerial phenomena possessing similar characteristics which have been observed in the New Mexico-West Texas area. The common characteristics . of most of the incidents are: Green color, sometimes described as greenish-white, bright green, yellow-green, or blue green. b. Horizontal path, sometimes with minor variations. c. Speed less than that of a meteor, but more than any mown type of aircraft. d. No sound associated with observations. e. No persistent trail or dust cloud. f. Period of visibility from one to five seconds. 2. All of the incidents reported do not possess all of the above onaracteristics, but in each case one or more are present. In none of the reported incidents has any natural or man-made object been determined to be responsible. The body of this summary consists of a tabulation of observations with notes attached to clarify or amplify certain of the more important observations. Note numbers 1, 3, and 5 are taken directly from reports compiled by Dr. Lincoln LaPaz, University of New Mexico. Dr. LaPaz is internationally known and respected as a meteoriticist, and has taken a great interest in these phenomena. The tabulation of sightings is not a conplete record of all re- ported observations, but comprises only those in which interviews werc conducted by OSI personnel. Many other persons were interviewed by Dr. LaPaz and his. colleagues, but inasmuch as complete data is not available, these interviews are not taken into account in this summary. In addition, numerous reports have been received from individuals who could not provide SHORT TULE: KY-5977 NW 91526

= EXTRACT FROM REPORT SUBMITTED BY DR. LaPAZ ON 20 DECEMBER 1948: Decomber 14: 1:00 a•m•, Mr. Mimo Sanchez (Wagon Mound, N.M.) The Real Path of the Only Green Fireball so Fer Observed at Two Separate Stations• Among the numerous observations so far mado, there is only one pair of corresponding observations i.e., those made simultancously by different groups of observers at widely separated stations. The only such observations are those obtained on the night of December 12 by one grou of observors near Starvation Peak (Bernal, New Mexico - see report on incit of 1948, December 12, 9h 2m plus or minus 30s), and a second pair of obser stationed within the Los Alamos reservation. By graphic reduction of the simultaneouly made observations, the following facts have been determined: The green fireball of December 12, 9h 2m plus or minus 30s appeared very nour a point with the coordinates latitude 35° 50', longitude 1060 401 and disan. peared near a point with the coordinates latitude 35º 45', longitude 107° U: traversing a nearly or exactly horizontal path with a longth of very nearly twenty-fivo (25) miles at an altitude above the surface of the earth of ap- proximately 8 to 10 miles, dopending on the estimate of angular altitude employed in the roduction; tho velocity with rospoct to the carth works out at between 8 and 12 miles a second, depending on the duration estimate used. It should be observed that the above results are obtained under the assumptior that the points of appearance and disappearance of the fireball were seon simultaneously by both the Bernal and Los Alamos groups. In case this assump tion is not fulfilled, the real path could very easily be no more than 10 to the velocity with respect to the earth then working out at 6 milos a second. While there is thus considerable undortainty because of the lack of confirming azimuth observations from a third station. concordance in the five (5) differont estimates of angular elevation make ic most unlikely that the linear height of the fireball was much less than 8 mi: and much more than 10 miles. extension of the 25-milo path first given passes almost contrally across the Los Alamos reservation. 3. Significant Differences Betweon the Fireballs Observed in the Intery: December 5-13 and Typical Meteors. 3.1 The horizontal nature of the paths of most of the December fire. balls is most unusual. Genuine meteors are rarely observed to move in hori.. zontal paths. 3.2 Again the very low height of the December fireball discussed in section 2 above sots it off in sharp contrast from the genuine meteors for which heights of the order of 40 or more miles are normally observed. 3.3 The velocity determined for the fireball of December 12 is much less than the velocities determined frum typical moteors (and yet is consider ably greater than the speeds of the V-2 Rockets or jet planes or of conventi flares) • NOTE 1 NW 91526

TO: Colonel Doyle Rees December 20, 1948 3.4 In the case of meteorites that penetrate to as low levels as that determined for the fireball of December 12, the observed luminous pho- nomena are always accompanied by very violent noises. No noises whatever have been observed in connection with the various December firchalls so fer investigated. 3.5 Genuine meteors normally show remarkable variations in orip..t.oe beginning as fine thin hair lines, which are scarcely visible to the obsorver, and then brightening up to flash out near the und of their paths. In tha mos. of the December fireballs most of the observers have reported that the grio. balls appeared almost instontly at their full brightness. 3.6 In the case of genuine meteors the paths are directed toweri all points of the compass with equal frequency. On the contrary in the cora of the green fireballs, plots of admissible approach sectors show that chur: is a very pronounced tendency for the paths to come in from the north hali of the sky• 3.7 The thrae groups of anomalous greenish luminous phenonona si w a curious association with well known meteor showers, although none of these meteor showers normally produce extremoly bright gruon firoballs, such ss those recently observed. For example, the observation mentioned by kir: apposred near the maximum of the quadrantid shower of carly Jenary, Mr. McCullough's observation of August was noor the time of the Persid shower duri the December observations all fell in the interval covered by the Gominia shower. This relationship might indieute an attempt to render the green for. balls less conspicuous by causing them to appear only when there is consider. able meteoric activity. 3.8 As noted in an earlier communication, the remarkably vivid greon color reported for most of the December fireballs is rarely obsorved in the case of genuine meteors. By laboratory test this peculiar color seems to bu identical with that given off by copper salts in the blowpipe flome, If baia identification is correct, the wovelongth of the radiation from the green fireballs is near 5,218 Angstrom Units. 3.9 The duration estimates of between 2 and 3 seconds reported fer the green fireballs are considerably longer than those (0.4 - 0.5 seconds) for the ordinary visual meteors, but shorter than the duration estinates invariably reported in the caso of a genuine meteorite fall (5 to 30 saceads or even longer). 3.10 For none of the green firoballs has a train of sparks or a disi cloud been reported. This contrasts sharply with the behavior noted in case of meteoric fireballs--particularly those that penetrate to the very low levels where the green fireball of December 12 was observed. 4. On the basis of the various differences to which attention is onl in section 3, the writer remains of the opinion that the fireball of December 12 was definitely non-meteoric and that in all probability the same is iru. of most, if not all, the other bright geen fireballs, which the OSI has her under investigation.

INCIDENTS OF 13 AND 20 DECE IBER 1948 : The unusual feature of these two incidents is that there were reportsi two red lights trailing the green fireball. In each case observers agree! that the trailing lights retained a constant position with respect to cs: other and to the green light. Also, these two sightings are the only bu all the green fireballs where a sharp change of direction in the vertior plane was observed.

SECRE COPY INCLOSURE #6 The University of New Mexico Albuquer que December 30, 194€ Institute of Meteorities TO: It. Colonel Doyle Rees, Commanding Officer District No. 17 Office of Special Investigations From: Lincoln LaPaz, Director Institute of • Meteoritics Subject: Anomalous luminous phenomena (Third Report) In the second report of this series, a description was given of the rea path through the atmosphere of the green fireball of 1948, December 12, ghi plus or minus 308). On the basis of corresponding observations made fron. cu station near Starvation Peak, New Mexico, and a second station near Los Alanc New Mexico, this fireball was found to have appeared near a point with the coordinates: latitude 35º 50' N, longitude 106° near a point with the coordinates: latitude 2, 401 W, and to have disaptor 451 N, longitude 107' 05 traversing an almost horizontal path, at an elevation of about 10 miles a sea level, with a length of about 25 miles, at a velocity of approximately 10 miles per second. (The minimum path length consistent with the observat was found to be about il miles, the correspording velocity then falling bet. 3 and 6 miles per second, depending on the duration adopted.) On the basis of corresponding observations of the greenish-white fix ba... of 1948, December 20, 8h 54m pem. made by two pairs of Los Alamos observers: t has now become possible to work out another approximate real path As w. ve apparent from the original accounts of the observations made by ABS: Inspectors William D. Wilson, Buford G. Truett, Clifford E. Strang, ara Pays:. Security Inspector George S. Skipper, the fireball of 1948, December 20 war observed under less favorable conditions than the green fireball seen by five persons on the night of December 12. However, on the basis of the origina: accounts of the observers named above, of sketches supplied by these four ir viduals on December 29 and of transit observations made by Captain M. 5. Nee and the undersigned on the same date at the points of observation iz. s 35° 481 . 9, 1060 181 .4 for Strang and Skipper and 35º 55', 106º 23' •1 for Wilson and Truett), it has been possible to establish reasonable concordance etween various points on the fireball path as seen by the two groups oi one servers. Because of the very short baseline only 8 miles lone between bi. two points of observation and the difficult conditions under which the first. of December 20 was observed, it is my opinion that the real path deraved iro: the December 20 observations deserves considerably less weight than that ch. tained from the December 12 observations.

Lt. Col. Doyle Reos - 2- December 30, 1918 It is found that the fireball doubly observed by Messrs. Wilson, Truett, Strang, and Skipper appeared at a height of at least 10 miles and descended u an angle of about 450 to the vertical (according to Truett's estimate) to • point C at an elevation of only 2.3 miles above the horizontal plane threr. the point from which Strang and Skipper observed. As the fireball approa the point C, its path levelled off and from C to its point of disapposranu E, the fireball followed a nearly horizontal path approximately 7.5 miles moving with a velocity of between 3.75 and 7.5 miles per second, dependini the duration estimate adopted. The coordinates of the projection of C on earth are 35º 56', N, 106º 30* W, and those of the projoction of E are 35° 571 N, 1060 231 W. The forward extension of the fireball's trace on the a as detormined by the above projections, passes some six miles to the nort. si the town of Los Alamos • It should be noted that the descending branch of the path of the firon:. was observed by Inspector Truett alone, but he was absolutely certain thes his observation of this portion of the path was correct. It should also be noted that no sound was heard, although the distance from the observers to in: fireball and from the fireball to the earth could have been only a few mitua I have no hesitancy in testifying that an object possessing the :.. path and the other peculiaritios observed by wessrs. Wilson, Truett, Strang, and Skipper was not a falling moteorite. SECRE NW 91526

TO: Director, Intelligence & Security Division 7 January 1949 FROM: Chief, Physical Security Branch SUBJECT: Reported Observation of Unidentified Light or Flare Moving Acros: the Sky on 6 January 1949 1. On 7 January 1949, the writer interviewed Pfc. Meredith J. Everitt, ASN 38552954, Headquarters, 8450th M.P. Group, concerning the un- identified light or flare which he had repertedly seen moving across the sky- 2. Pfc. Everitt advised that on 6 January 1949 he was guarding a C-97 airplane at the landing strip, located adjacent to the Ordnance Area, when at approximately 1730 hours he noticed a bright object travelling across the sky, from the Southeast towerds the Northwest. He related that the object was diamond shaped, approximately two feet long, and appeared to be much brighter in its center than at the edges. He estimated that the object was approximately 1500 to 2000 feet in the air and travelled approximately 500 feet, horizontal to the carth's surface, before he lost sight of it. Everitt was unable to estimate the speed of the object but stated that he has seen low flying jet planes, and that this object travelled much faster than the jets that he has observed. There was ne smoke or other vaporous naterial visible to Pfo. Everitt around or following the object. At the time Pfc. Everitt witnessed the object, he stated thot the sky was clear, furnishing a light blue background, and that the object appear- ed to be a bright white light, with no other apparent visible color. 4. Standing guard with Pfc. Everitt were Sgt. Richard Woleslege and Cpl. Wilson, and according to Pfc. Everitt, neither of the other men saw the object. Everitt explained that he called to Sgt. Woleslege, who was standing at the other end of the plane, and told him to look at the object in the sky, but by that time it had disappeared. 5. Pfo. Everitt stated that he attendod Flight School, under the G.I. Bill of Rights in Houston, Texas, during the year 1947, and that he has had some experience in observing aircraft. /s/ MATTHEW J.

THE UNIVERSITY OF NEW MEXICO ALBUQUERQUE Institute of Meteoritics TO: From: It Colonel Doyle Rees, Commanding Officer District No. 17 Office of Special Investigations Lincoln LaPaz, Director Institute of Meteoritics Fobruary 21, 1949 Subject: Anomalous luminous phenomena (4th report) 1. Several additional sightings of unexplained aerial light phenomen have occurred since the third report in this series was prepared. Outstandin among the as yet undescribed incidents was the green fireball of Sunday eveni.. January 30, 1949, 5:54 p.m• MST• Within less than one minute after the ap.. pearance of the fireball, an eyewitness (Mr. Nesbett) called to report the :» pression of a group of persons who saw the fireball through an east window while seated about the dinner table in a brightly lighted room. Within twelv hours after the fireball appeared, more than 100 eyewitness accounts had bor obtained by its director through personal interviews. An unusually high per. centage of the reports came from military personnel (waiting out under the s? for Post Theaters to open), from guards and other spocial agents already al. to watch for anomalous luminous phenomena and from airplane pilots, contre. tower men and oilwell workers working on the late afternoon to midnight shift. 2. On February lst, a staff car was placed at the writer's disposal by Major William Godsoe of the Fourth Army and a field survey was begun of che region in New Mexico and Texas in which the majority of the observer's repor... ing the fall lived. This survey, carried out under unusually severe weather conditions, included visits to the following localities: Moriarty, Estanci: Vaughn, Ramon, Mesa, Roswell, Caprock, Tatum and other towns in New Mexico: and Lamesa, Brownfield, Plains, Lubbock, Muleshoe and other towns in Texas: (Several of these towns were visited two or more times.) At Roswell, where very effective cooperation was provided by the OSI group at Walker Air Base under Lt Paul Ryan, and the local CAP unit under Lt II. K. Cobean, Special Agent Bill Ricket was added to the survey party and gavo much aid in late: work. At Lamesa, Texas, the ground survey party was joined by an air sear i party consisting of Major Charlos Phillips, USAF, Captain Melvin E. leef and Special Agent Jack L. Boling, from the 17th District OSI offico at Kirtlani a low-level air reconnaissance mission in a T-ll aircraft over the urea sur- rounding the earth-point of the fireball of January 30th. At the same tama a second ground survey party under Lt Paul Ryan made a careful field scarch along a route extending from Lamesa through Amherst, Texas, to Clovis. Wow Lu NW 91526

• 3. As a result of the ground and air searches referred to above, and of an analysis of the very large amount of information obtained from eyowitnessos by personal intorviows, by telephone conversations and by letter, it has now (three weeks after the fall) become clear that several thousand persons in New Mexico and Texas saw this great fireball leisurely treverse the sky. It has been possible to detormine that the Jenuary 30th fireball became visibl at an altitude of approximately twelve miles over a point at latitudo 349 Done tudo it at latata disappeared at en altitudo or approximatoly olent me: 48', longitude 102º 22', after traversing a nearly horizontal path approximately 143 miles long at a velocity of from s to fourteen miles per second. Although the January 30th firoball must bet a among the brightest observed in the last quarter-century, and in spito of th fact that its real path lay closer to the earth throughout its ontire extor than any other meteorite path of which the writer hes knowledge (excepting 90.3 the anomalous green fireballs of December 12th and 20th, 1948), the meteor. detonations and long continued rumblings which without excoption accompany large moteorite falls were not observed on January 30th by anyone in the vo. large region covered by the various ground surveys. However, what may have been Udden noises (anomalous whizzing and hissing sounds frequently roporcon by very distant observers as having been heard at the same time that a metes.. ritic fireball was seon) wore hourd at Roswell, New Mexico, and neur lulosh: Texas. 4. paragraph, the fireball of January 30th, 1949, shows several other features (e•g• nearly horizontal path, absence of long enduring luminous train or du.' clouds, North to South direction, oto) characteristic of the green fireballs earlier described in this series of reports. However, the January 30th firo. ball was much brighter than any of those earlier reported and differed from b other green fireballs in that many of the Texas observers who were situated nearest its path reported its color as blue, orange, red and even purple in- stead of green. 5. Up to the presont time (February 21st), no evidence whatever supports: the belief that solid fragments fell to earth from the January 30th firebel: has been discovered. However, as promptly as possible, a much moro thorough ground search should be made in tho probable area of fall as outlined by ti earlier surveys, for, in my opinion, the fireball of January 30th is the only one of the anomalous luminous objects undor investigation which gives any in cation of having boon a meteorite fall. 6. With the present report, the writer's participation in the OSI's in. vestigation of the puzzling fireball question must, to his rogret, terminato During the time I was on leave of absence from the University of Now Mexico, was glad to donate my time and services to this investigation. Now that I ar again serving as Head of the Department of Mathematios with a full time tese, i load, it is impossible for me to continue cooperating with the OSI• LINCOLN LaPAZ Head of Dept of Mathematics.

doet L01 4 -coples, Series age Report of Trip to Los Alamos, 16 Feb 49 (Cont.) 18 February 1949 Dr. LaPaz stated that he had been assisting the Military for the past two months at their request in the investigation of the subject problem, and went on with the general discussion of phenomena attending normal meteorite fall, postulating the following important character- istics: 8. Random path of fall. bo Color and intensity variations in light emitted. c. Sound. d. Frightened animals. 4. Dr. LaPaz then went on to discuss the number of observers re- porting the subject phenomena and the diversity of their backgrounds, including commercial airlines' pilots, military pilots, special intelligence agents, Los Alamos personnel (Mr. Hoyt), and himself, as well as various and sundry previously uninformed citizens. 5. Dr. LaPaz then described the "Starvation Peak Incident" which he observed himself, detailing the following characteristics which indicate that the phenomenon can not be classified as a normal meteorite fall: a. Initial bright light (no period of intensity increase) and constant intensity during the duration of the phenomenon. bo Yellow-green color (about 5,200 angstroms). c. Essentially horizontal path. d. Trajectory traversed at constant angular velocity. e. Duration about two seconds. f. No accompanying noise. 6. Since about 5 December 1948, there have been more than ten in~ cidents analogous to the "green fireball" described, and some twenty more presenting minor deviations to the above, which should be considerod in connection with them. In addition, there have been a number of normal shooting stars and meteors observed. There ensued a general discussion in which it wes brought up that the majority of the observers whose reports were here under consideration were not subject to previous psychological influences or prior knowledge as to what they should look for.

4 age. Report of Trip to Los Alamos, 16 Feb 49 (Cont.) 18 February 1949 average during December, January, and February, yet no green fireballs have been reported in any other areas. They seemed to be confined to the Los Alamos, Las Vegas, and Vest Texas triangle. Mr. Teller then took over the discussion and showed that a material object travelling with the velocity of the subject phenomenon (about eight miles per second) would have to have a mass of about twenty grams, assuming all the kinetic energy coula be converted to fight, unde the assumption that the light output is in the vicinity of 10 ergs per second. He then went on to show that the shock wave produced by the passage of an object of these dimensions or greater passing through the atmosphere at a height of eight to ten miles (the observer figures) with a velocity of eight miles per second would produce a loud noise easily audible ten kilometers from the source. No sound has been observed. Therefore, Mr. Teller has the tentative opinion they are not material objects passing through the air. We should look to electronics and optics for an explanation rather than in the field of hydrodynamics. In any event, it was apparently agreed by those present that it was almost incredible that a large object such as a guided missile or informer vehicle could pass through the atmosphere at a height of eight miles at a velocity of seven to eight miles per second without producing a loud noise which would have been audible to observers. Mr. Bradbury demurred so fer as the electronic explanation was concerned, saying if it were assumed that the answer lay in that region, many more difficult problems would have to be solved. 9. The following action seems in order: 8. Recalculation of the data outlined by Mr. Teller with a more accurate treatment to verify his tentative conclusions. b. The establishment of well-equipped and organized observation stations to give as thorough photometric and photographic coverage as is possible in the geographic area involved. c. Assuming that Mr. Teller's theories are borne out by re- caiculation, declassification of the Project to permit participation and thinking by scientists throughout the country• 10. Dr. LaPaz and Captain Neef have fruitlessly attempted to obtain information from a meteorite observers' group now at White Sands, said to be performing work under contract for the Navy. Commander Mandelkorn offered to assist them in their endeavor to enlist the services of the group for observations in connection with Project "Grudge". 11. Conclusion: It is my belief that these phenomena, *particularly if there are any further incidents, are deserving of serious consideration *See next page. -3 - NW 91526

Although Mr. Teller's discussion tends to disprove the hypothesis that guided missiles or informer vehicles are responsible, there is cause for concern of the continued occurrences of unexplainable phenomena of this nature in the vicinity of sensitive installations. *Captain Neef reports blue fireball visible from Sandia at 0530, 17 February 1949, and a yellow-orange cigar-shaped light at 1759, visible /s/ Richard Mandelkorn RICHARD MANDELKORN, Commander, U.S.N.

The purpose was to check the powers of observation of observers who had previously reported the phenomena observed on 6-7-8 March 1949 and heretofore reported in Summary of Information, this headquarters, dated 17 March 1949. subject: "Unusual Lights." However, before this operation could be begun, the series of 8 unusual "lights" appeared.

Time was clocked at instant of sighting. Captain McCullough, the Assistant G-2, personally observed three of the lights. Physical character- istics of these "lights" were reported as "quite different" fron those reported on 6-7-8 March 1949. One burst into a green cluster. One was reddish, another white. One observer described some of them as similar to Very Pistol flares. While this phenomens was occurring, a security detachment from the "Q" area. arrived in the vicinity of the alert crew fron the 2nd Amored Division. DISTRIBUTION -AGO FORM WD 130 47 568 ucl#3 U. S.

AT GANP HOOD, it was deternined that this type of phenonens, hitherto unreported from the Camp Hood Area, has the sime general characteristics of the phenomena observed during the past several months at Sandia Baso. Because observers were in different locations and some wore not certain as to time, it is possiblo that observation reported within the sane hour on the sune date are duplications. It should be noted that none of the observers had been instructed to look for or report any sort of atnospherie phenonenn. All stated without equivocations that they had never before seen anything resembling the reported phenomena. All claimed to have seen "falling stars" nearly every night on the Camp Hood Reservation; but all wore emphatio in stating that this phenomena was quite different. All men were interrogated separately and had no advance notice that they would be questioned. After the interrogation they were taken to the spot where the observations had been made. These points were nunbered and then plotted on map, Camp Hood and vicinity, 1/62 500 1913. Ovorlays have been made and a copy is heroto attached. The observer was then told to ain a surveying instrument, brought along for the purpose, at the colestial points of origin and of temination of the phennens. Vertical engles and magnetic azimuth of each point was then recorded. In most cases, the observer was able to fix azimuths by sone terrain features. Vertical angles were of course estinated except where elevations of observations coincided with ridge on tree lines.
