The r ed fire- ball occasionally re- ported he believed ,.,as the visual after-effect of the green.

IW"ly ot· the sightinf;S are attributable to natural ohcnoruena such as • flight 0~ o1r ds, planets, meteors, and possib~y cloudiness. Dr. Fred L. \Ihi pole of Harvard , in a memorandum to t his lo.bo1·atory dated 9 J~urrt.tst 1950 relative to this problell, indicated that he had observed a tendency for the occurrence of small detachea clouds in Hou l ~xi co Hhich might have been mist~en for an aerial object when illuminated by the reflected light of the moon. Dr. .hipple investigated the possibility of a cor- relation between the frequency of aerial pheno~ena observations and weather conditions -- specifically cloudiness . A rough analysis of available \reather data, in ... icated that on the 53 nights (bet\veen 5 December 1948 and 5 March 1951) vrhen observations were r eoorted, 10 were clear, · 4 partially cloudy, 5 cor.1pletcly overcast and 14 had no record. The nt~ber of cloudy nights i nvolved seems unusually hirh for New I:exico. The weather reports vrere for the Las Cruces Ar~a only where- as many of the observations were a considerable distance from Las Cruces . li'urther investigation is therefore necessary to determine correlations • with cloudiness. ur. Uhiople also conducted a study us to \Jhethcr tho ar:e of the moon was related to th0 frequency of aerial phenomena observations. The res~ts did not indicate that the phenomena were observed largely at fUll moon. The stctistics show th8t of the 72 observations reported, 45 occurred when the moon was uo 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. lhipple suggests that the existence of moon- light is correlated with the ohenomena. Dr. \lhipple 1 s frequency diagrar1 of observations vs. age of moon is included in.tbjs report. ~ - - _ 'AT 8 YEAR INTERVAT~S: AFTER 12 YEARS. PIB 6200.10 ·~· .

It should be noted that Dr . Jhipnle made a cnre~ study of
meteor photogranhs tru{en in I;ew hexico on 35 nirhts when observations
Here reported.
None of the nhotographs revealed the. pr0sence of un-
usual sky phenomena .
Finally, the overall picture obtained from the year of vigilance
and inquiry does not uormit a conclusive opinion concerning the aerial
ohenomena of interest.
The comparatively hif;h incidence of tl1e ~heno-
mena since 1948 does not necessar ily indicate that the objects are
man-made. It is conceivable that the earth may be passing through a
ree;ion in space of high r.1eteoric pooulation.
Also, the sun- spot

ONCLASSIFI (1) No fur vher f i scal 0xnenditure be nmde in pursuin~ the problem. This opinion is proupted nartly by the fruitless expenditure durinp t he past year, the uncertainty of existence of unexplainable aerial • objects, and by the inactive position currently tal\en by Holloman AFB as indicated by the ''stand- by status· of the TJroj ct. The arrangements by HAFB for continued vigi lance by Land-Air, the weather ststion as well as the briefing of pilot s on t he problem in part r elieves the need for a systematic i nstrumentation program. (2) \ i thin the next fevr months, Dr. Uhipnle will have completed the installation of two 18-inch Schmidt cameras for meteor studies. rrbe cameras will be stationed about ?Q mil es apart in the vicinity of Las Cruces, New Hexico. Since these studies l.il l be sponsored by the GRD, arrangements can be nade for examining the film for evidence of aerial object phenomena.

Kodis Wright-Patterson Air Force Base, Dayton, Ohio "If no fire balls are observed in the next six month period, it is reconnnended that the project be d)scontinued. In a phenomenon as sporad.ic as the :t'iJ.'"C balls appear to be, it is felt that at least one year is required in order to establish '"hether their occurrence is or is not a seasonal phenomenon. 4. There is considerable doubt in the minds of some of the project personnel that this is a natural phenomenon. As long as a - --c: reasonable doubt exists, 1 t is not wise to d).scontinue entirely the observations. Dr . Whipple s suggestion that these may be moon reflections on small clouds cannot be discounted . That fire balls have been observed in the past cannot be di.scounted due to the re- liability of' several witnesses. It may be considered significant that fire balls have ceased abruptly as soon as a systematic \vatch vras set up. At present it does not appear likely that the next six months of observations will yield any more information than the first six months, but it is felt that even oegati ve inf6rmati.on may be significant . 5. It is requested that a six month extension of the Land Air contract be negotiated. It is also requested that the spectrographic equipment abando~ed by Holloman Air Force Base due to lack of personnel be turned over to Land Air for operation in the next six month period. At the conclusion of the six month extension, an evaluation of the observations will be accomplished by this Directorate and reconunenda- tions as to the future conduct of this project will be forwarded to your cOimnand.

In accordance with instructions contained in classified letter from Chief of Staff, USAF to CG, AMC, s1bject 11Light Phenomena," 11+ September 1949, the undersigned attended a conference at Los Alamos on the subject of a phenomena observed in the northern Nevr Mexico area. The phenomena has the appearance of a green fireball and because of the fact that it has been observed only (as fa.r as can be determined) in the northern new Mexico area and only since the year 1947, has caused a high degree of apprehension among security agencies in the area. Two reports from the 17th District Office of Special Investigations (inclosures 1 and 2) summarizes present information on the phenomena. In view of the fact that the phenomena has been observed by independent and t~ained observers there is little doubt that something was actually observed. 2 . Inclosure 3 lists those personnel attending the conference. 3. The first part of the conference was devoted to a sununary pre- sentation of all collected and organized observational information re- garding green fireballs . The presentation wa.s made by Dr. Lincoln LaPaz (Professor and Head of Department of Meteroritics and Mathematics: Uni- versity of New ~exico) and Capt. Melvin E. Ncef (17th District OSI, USAF). Dr . LaPaz has been cooperating witl1 the OSI investigators in the matter at their request and on an unpaid basis . Capt. Neef 1s the principal OS! agent on the case. Both Dr. LaPaz and Capt Neef have personally and independently observed the phenomena. 4. The second part of the conference was a discussion by the scien- tists present of various possible explanations and hypotheses concerning the phenomena.

• • • • • • c 0 p y • ll ABSTRACT • Early in 1950 the Geouhysics Hesoarch Division received a directive to investigate peculiar li ;ht nhenomena that had been observed in the skies of the southwestern United ~tates • • Project '!\-Tinkle \o~as established to check into these phenomena and their exnlanation. The pist of the findings is essentially negative. The period of observation" covers a little over a yea:r. Some unusual pheno- mena were observed durinrt t hat period, most of then can be at- tributed to such roan-made objects as airplanes, balloons, rockets, etc . Others can be attributed to natural nhenomena such as flying birds, small clouds' tllld meteorites . rrhere has been no in- dication that even the somewhat strange observations often called Green Fireballs · are anythine but natural ohenomena. Our recommendations are in essence that there is no use in sinking any more funds into this at the present time and that \.re \trill keen in connection with one of our meteor studies a sharp eye on anythin~ unusual a~ong this line.

Freder ic C.E. Oder of CR.U attended a con- ference at los Alamos, 14 October 191,.9 on the subject of 11Green Firebal.ls' observed in the Northern New Hexico area . Since the phenomena had been observed only in this area and only since 1947, it had caused considerable concern among security agencies in the area . It \vas the conclusion of the scientists present at this meeting that the information available waR not sufficiently Instrmnental observations - photo- graphic , triangulation, and soectroscopic were considered essential. Dr . L. La Paz of the Denartment of Ueteori tics of Univ . of Ne¥1 J.1exico Has present at the Los Alamos meeting and subsequently \-Tas in- vited to suh~t pr oposals for studying this ohenomena under GRD spon- sorship. On 2 February 1950, Dr. La Paz advised that due to diffi- cul ties with academic arraneements , he \vas unable to undertake this study.

facilities for the electromagnetic f r equency me..asurmaonts that were
to be )rovided by the Signal Coros ~ngineerine Laboratories were not
utili zed due to the fact that the frequency of occurrence of these
phenomena. did not justify the

Ho ,o~ev er, the phenomena activity over Holloman AF13 150 miles

consider ed sufficiently significant so that the contract with Land-Air
