ABSTRACT
i
Early in 1950 the Geophysics Research Division received
a directive to investigate peculiar light phenomena that had
been observed in the skies of the southwestern United States.
Project Twinkle was established to check into these phenomena
and their explanation.
The gist of the findings is essentially negative. The period
of observations covers a little over a year. Some unusual pheno-
mena were observed during that period, most of them can be at-
tributed to such man-made objects as airplanes, balloons, rockets,
etc. Others can be attributed to natural phenomena such as
flying birds, small clouds, and meteorites. There has been no in-
.dication that even the somewhat strange observations often called
'•Green Fireballs'11 are anything but natural phenomena.
Our recommendations are in essence that there is no use in
sinking any more fluids into this at the present time and that we
will keep in connection with one of our meteor studies a sharp eyo
on anything unusual along this line.

facilities for the electromagnetic frequency measurements that were to be provided by the Signal Corps Engineering Laboratories were not j utilized due to the fact that the frequency of occurrence of these ' ;| phenomena did not justify the $50,000 a year transfer of funds to the ^ j Signal Corps which would be required to carry out such a monitoring • I facility. However, the phenomena activity over Holloman AFB 150 miles ; south of Vaughn, N. Mexico during the latter part of iugust 1950 was ;j considered sufficiently significant so that the contract with Land-Air : » • . : . ; (Askania cameras only) was extended for six months ending 31 March 1951* ' 3» Contractual Period - 1 October 1950 to 31 March 1951 . Because of the dininution of phenomena activity in the vicinity ^ ' of Vaughn and the resumption of activity near HAFB, the Askania cameras again were overhauled and installed at HAFB. This installation was completed about 5 November 1950. On 16 October 1950, arrangements were made by Lt. Albert of HAFB that Northrup Aircraft pilots engaged in frequent flying of B-45 and QF-SO aircraft in the Holloman vicinity • ' would report all observations of aerial phenomena. • During this period, occasional reports 1.;ere received of individuals seeing strange aerial phenomena, but these reports were sketchy, in- conclusive, and vere considered to be of no scientific value. Ho v sightings vere nade by the Askania cameras. Nothing whatsoever was reported by the Kbrthruo pilots. Popular interest seemed abated, at least in the southwest. On 31 March 1951, -due to the expiration of the contract, Land-Air ceased constant vigilance at the two Askania sta tions. In sumnary, the results during this period were negative.

2. Contractual period - 1 Anril 1950 to 15 September 1950•• Some photographic activity occurred on 27 April and 24- May, but simultaneous sightings by both cameras were not made, so" that no information vas gained. On 30 August 1950, during a Bell aircraft miesile launching, aerial phenomena were observed over Holloraan Air Force Base by several individuals; however, neither Land-Air nor Project personnel were notified and, therefore, no results were acquired. On 31 August 1950, the phenomena were again observed * after a V-2 launching. Although nueh film was expended, proper * •.-•+•' ^'* triangulation was not effected, so that again no information was acquired. On 11 September, arrangements were made by Holloraan AFB for Major Gover, Command e,r 93rd Fighter Squadron at Kirtlend A^B, to be on call so that aerial objects might be pursued. This would make possible more intimate visual observation and photography •at close range. Major Gover was not authorized to shoot at the phenomena. Generally, the results of the six-month contractual period may be described as negative. Although the photographic theodolites functioned continuously, the grating cameras functioned very little, since the military personnel assigned to operate them had been with- drawn due to the needs concerned with the Korean situation.

These data then would be used to demonstrate the need for initiating * I ' a study of the phenomena. On 21 February 1950, an observation outlook I * post was set up at Holloman Air Force Base manned by two personnel. •I ' ' • . i Observations with theodolight, telescope and camera were undertaken, between the hours of sunrise and sunset. On 5 March 1950 a conference was held at IJright-Patterson Air Force Base which included Holloman Air Force Base and GRD personnel. . Action wa» taken to initiate a three point program which was confirmed by AnC in the form of a letter directive on 16 March 1950, subject rlight Phenomena1'. t a. Askania instrument triangulation by Land-Air Inc. b. Observations with Mitchell camera using spectrum grating by Holloman Mr Force Base personnel. c. Electromagnetic frequency measurements using Signal Corps Engineering Laboratory equipment. • Under contract to GRD, Land-Air Inc. was required to maintain constant watch at two Askania stations for a six-month period. Since an abnormal number of reports had been received from Vaughn, New Mexico, it was decided to install the instrumentation at Vaughn. UNCUSSIFIED

I 1, Background In accordance with instructions contained in a classified letter « ^ • ' from Chief of Staff, USA? to CG, AMD, subject '"Light Phenomena", on 14 September 1949, Lt. Col. Frederic C.E. Oder of CRD attended a con- . ference at Los Alamos, 14 October 1949 on the subject of '"Green Fireballs" observed in the Northern New Mexico area. Since the phenomena had been observed only in this area and only since 194-7, it had caused considerable concern among security agencies in the area. It was the conclusion of the scientists present at this meeting that the information available L*i\frt.-'"' was not sufficiently quantitative. Instrumental observations - photo- Wv;>" graphic, triangulation, and spectroscopic were considered essential. v Dr. L. La Paz of the Department of Meteoritics of Univ. of New Mexico was present at the Los Alamos meeting and subsequently was in- vited to submit proposals for studying this phenomena under GRD spon- sorship. On 2 February 1950, Dr. La Paz advised that due to diffi- culties with academic arrangements, he was unable to undertake this study. During February 1950, the frequent reports of unexplained aerial phenomena in the vicinity of Hollonan Air Force Base and Vaughn, New Mexico prompted the Commanding Officer of Holloman Air Force Base to initiate a program to gather factual data. • f< UNCLASSIFIED

4. 'Post Contractual Inquiry In view of the unproductive nature of the contract with Land-Air,, i it was decided to make further inquiry concerning recent aerial object 1 developments in New Mexico. On 9 August 1951, the situation was discussed ; with Lt. Col. Cox of the 17th OSI District (Kirtland AFB). Until 15 March j; 1950 the District had been diligent in forwarding copies of their reports ; '! on aerial object phenomena. Since then, no reports have been received I by 'the Geophysics Research Division. Colonel Cox advisedHhat reports i . •'/ ' of strange aerial phenomena were still received by the 17th OSI office, H at the rate of once or twice a month but little attention was being given ! to this matter. Most of the reports originated from personnel at Los Alanos. The OSI files were reviewed. (A summary covering recent reports ? Jr* ' ' ' i ,<>*>' is attached.) It was learned'' that reoresentatives from LIFE and also "V .from ARGOSY were interested in publishing articles on aerial object phenomena. On 27 August 1951, developments concerning aerial phenomena were discussed at Holloman AFB. Lt. John Albert previously associated with the project had now been transferred froia Holloman. Therefore, the project was discussed with Major Edward A. Doty who had assumed respon- sibility. Major iJoty, who seewed to be thoroixghly acquainted with the situation, advised that there have been very few reports of DOWNGRADED AT-3 YEAR INTERVAL DECLASSIFIED AFTER 12 YEARS.

aerial phenomena in the vicinity of Hblloroan since September 1950. The populace around HAFB seem to have lost their sensitivity as ob- servers. Even during the meteor shower of 11-12 -August 1951, no alarming reports were received. However, on 14 March 1951, nine « Bell personnel reported sighting between fourteen and twenty bodies , "not unlike a flock of geese;l. On 9 July a '"red glowing ball1" was ! sighted by a sergeant stationed at the Corona i&per^Lmental Radar ,, Site at Corona, New Mexico. (Copies of both reports are attached). : More .recently, a pilot reported sorae aerial objects which, after ( investigation, were identified as planets. • (; Mr, 3. Guildenberg, who is an assistant to Major tbty and an !i £ active amateur astronomer, comnented that he has been spending sev- «' era! hours at his telescope almost, every night for the past few years and never once observed, an unexplainable object; that on one occasion, an excited acquaintance was pacified when a '"strange object" showed up as an eagle in the telescope; that Clyde lombaugh, discoverer of the planet Pluto and now engaged in activities at V/hite Sands, never observed an unexplainable aerial object despite his continuous and extensive observations of the sky; that Fred Uhipple in his work photographing meteors at Las Cruces, never de- tected a strange aerial object with his Schmidt cameras; and that the A and M College at Las Cruces engages in astronomical observa- tions but had never observed strange aerial phenomena. .

/ it was learned from Major Dotyj that Col. Baynes, C. 0. at
HAFB, no longer felt there was any justification for the allocation
of funds for maintaining systematic investigation. Rather, he provided
that the project be maintained on a standby basis and without official
Air Force status, '-^nis entails assignment of an officer (Major Itoty)
to collect incoming'reports, make periodic review of the files '"for
I
patterns or persistent characteristics in the reports'", maintain
liaison with OSI, Provost Marshall's Office and any other agencies
V '
whose activities may serve to provide information concerning future

t
t.
aerial phenomena developments. Land-Air has agreed to report and
('
if possible photograph any abnormal sightings made during their scheduled
periods of operation (about eight hours each...day). The weather station
will function similarly. Also, all pilots have been briefed to report
any unusual observations. If necessary, the project can be activated
very quickly, even to the extent where funds will be made available,
for the purchase of equipment.
Major Doty also arranged a conference with Mr. Warren Kott, who 1
is in charge of land-Air operations. Mr. Kott pointed out that a formal}.

this could be done by Land-Air at the additional expense in the near future when the work load diminished. Mr. Kott requested formal authorization to do this and Major IJoty agreed to issue this letter « s* '•''"•.•'• of authorization. It was arranged further that at such time when the study is completed all photographic and tape record5.ngs would , be sent to the Geophysics Research Division. Prior to departing HAFB, the project files were reviewed. Major Doty advised that access to the files had not been requested by any periodicals. On 28 August 1951, the subject was discussed informally with Dr. Lincoln La Paz, who expressed disbelief in all aerial phenomena t except for the green fire-balls. The red fire-ball occasionally re- ported he believed was the visual after-effect of the green. Their recent origin (194-7) and peculiar trajectories did not permit, accord- ing to Dr. La. Paz, them to be classed as natural phenomena. The most recent that has come to his attention occurred over Detroit 'on 7 July 1951. It crossed the city from Northwest to Southeast with a sharply descending trajectory which leveled out and was observed by many residents of the city. Dr. La Paz expressed the opinion that the fireballs may be of our own military origin, but if not, they are a matter of serious concern. 5. Conclusions .. Undoubtedly, a good many ol' the observations reported are attri- butable to ordinary man-made objects such as airplanes, balloons, smoke rockets, etc. It appears that balloon observations especially are re- sponsible for a large number'of the reports.' The possibility of small .-,.,-. DOWNGRADED AT 8 YEAR II 8 UNCLASSIFIED

emissive olouds issuing from atomic installations also has been'proposed. Many 61' the sightings are attributable to natural phenomena such as . flight of oirds, planets, meteors, andC possibly cloudiness. Dr. Fred t. Whipple of Harvard, in a memorandum to this laboratory dated 9 August 1950 relative to this problem, indicated that he had observed a tendency for the occurrence of small detached clouds in Hew Mexico which might have been mistaken for an aerial object when illuminated by the reflected light of the moon. Dr. Whipple investigated the possibility of a cor- relation between the frequency of aerial phenomena observations and * weather conditions — specifically cloudiness. A rough analysis of available weather data, indicated that on the 53 nights (between 5 December 1948 and 5 March 1951) when observations were reported, 10 were clear, 24. partially cloudy, 5 completely overcast and 14 had no record. The minber of cloudy nights involved seems unusually high for New Mexico. The weather reports were for the Las Cruces Area only where- as many of the observations were a considerable distance from Las Crucos. Further investigation is therefore necessary to determine correlations with cloudiness. Dr. Whippie also conducted a study as to whether the age of the moon was related to ths frequency of aerial phenomena observations. The results did not indicate that the phenomena were observed largely at <L full moon. The statistics show that of the 72 observations reported, 45 occurred when the moon was up and 27 when it was down with many of the observations" occurring at the time of the moon's first quarter. From the statistical study, Dr. V.hipple suggests that the existence of moon- light is correlated with the phenomena. Dr. Vhipple's frequency diagram of observations vs. age of moon io included in._thls report. ' 1
Page 13
UNCLASSIFIED , It should be noted that Dr. VJhipple made a careful study of meteor photographs taken in Hew Mexico on 35 nights when observations * ^ •' •' • » were reported. None of the photographs revealedtthe presence of un- usual eky phenomena. . Finally, the overall picture obtained from the year of vigilance and inquiry does not permit a conclusive opinion concerning the aerial phenomena of interest. The comparatively high incidence of the pheno- x - . mena since 194-8 does not necessarily indicate that the objects are > man-made. It is conceivable that the earth may be passing through a / . region in space of high meteoric population. Also, the sun-spot ' maxima in 194-8 perhaps in some way may be a contributing factor. 6. Recommendations. Since the findings to date cannot be considered conclusive, it appears that the following recommendations would be pertinent: DOWNGRADED AT 3 YEAR INTERVALS- !

' The above personnel are located at the Bell Hardstatid awaiting the return of B-50 lib. 6002, following the completion of a Captive Flight mission. Mr. Heskew made the first sighting at approximately 1500 hours while following the flight path of the B-50, which at that time was flying on a southerly heading at an altitude of approximately 15,000 feet NSL east and slightly south of the base. At the first sighting due neither to the distance involved or small individual size of the objects, Mr. Heskew attached little significance to the phenomenon thinking perhaps that it was a flock of birds at a.considerable distance. However, in a minute or so he began to think otherwise and called the matter to the attention of Messrs. Lane and VJeber. At the time his sighting was verified by the latter two men, the elevation angle of the bodies appeared to be greater than that of the B-50 which had progressed a few miles further south and east of the Field. , The motion of the bodies (estimated at between 14. and 20 in number) appeared to be of a swirling nature, not unlike a flock of towering geese or a handful of leaflets in an up-draft. Either due to distance or size, it was impossible to resolve individual shape, however, the general impression was gained that the bodies were white. Several minutes after the first sighting the writer and others were apprised of the phenomenon. At this time, the B-50 had turned to the left on a reciprocal heading and was approximately east of the Field at the same altitude. The bodies continued to swirl in somewhat random fashion and increase apparent elevation angle. During this tine UNCLASSIFIED -8 • ' J

1, Since the establishment of the special project-at Hq AtfC,.
(Project GRUDGE), to investigate and analyze reports on so-called "Flying
eaucera" and unidentified aerial phenomena, many reports have been
,
received through Intelligence channels from persons Vfho'ha^o. obsorvdd
what they considered to be unusual li^at phenomena,•;''Foremo«b in this
•" . '
categqry have been those which are described as "green firaballs"v
,
, ' .
2. Analysis by various specialists has indicated that many of the ..';•
incidents involving light phenomena were undoubtedly observations of
natural phenomena. Particular attention was ;given to the "green fire-
ball" variety by Dr. Joseph Kaplan, member of the USAF Scientific
Advisory Board. Dr. Kaplan has concluded that the "greon fireballs" '
•
are natural phenomena.

3• Correspondence relative to t)r* .Kaplan's' conolusiohc on tho
phenomena .and corresoor.dence relative to a request from the Second
'
.
Armored Division, Camp Kood, Texas, for scientific investigation of
similar phenomena, are forv/arded for your information^
/».. The Air Materiel Command has under contract several organi-
zations in the Boston area that are specialists in observing tochniqucs
;
and the interpretation of celestial phenomena. It is desired that
these organizations be consulted regarding the "green fireball"
phenomena. If necessary, considdration should.be given .to-the'establish- ;
ment of an observational program designed to obtain additional
• ^
:
information necessary to an exolanatiori of the phenomena.

The phenomena has the appearance of a gj^een fireball and because of the fact that it has been observed only (as'Tar'^ITcan'be determined) in the- northern lletf Mexico area and only since the 'year 19'*7>. has caused a high ''-. degree of apprehension among security agencies in the area.
