# Office Memorandum • UNITED STATES GOVERNMENT TO : D. M. Ladd FROM : DATE: August 23,1950 A. H. Belmont SUBJECT: SUMMARY OF AERIAL PHENOMENA IN NEW MEXICO MISCELLANEOUS - INFORMATION CONCERNING ## PURPOSE To advise that: (1) OSI has expressed concern in connection with the continued appearance of unexplained phenomena described as green fireballs, discs and meteors in the vicinity of sensitive installations in New Mexico. (2) Dr. LaPaz, Meteor Expert of the University of New Mexico, reported that the phenomena does not appear to be of meteoric origin. (3) OSI has contracted with Land-Air Inc., Alamogordo, New Mexico, to make scientific study of the unexplained phenomena. NATURE OF PHENOMENA Heasly Observations of aerial phenomena occurring within the vicinity of sensitive installations have been recorded by the Air Force since December, 1948. The phenomena have been classified into 3 general types which are identified as follows: 1. Green fireballs, objects moving at high speed in shapes resembling half moons, circles and discs emitting green light. 2. Discs, round flat shaped objects or phenomena moving at fast velocity and emitting a brilliant white light or reflected light. 3. Meteors, aerial phenomena resembling meteoric material moving at high velocity and varying in color. The above phenomena have been reported to vary in color from brilliant white to amber, red and green. Since 1948, approximately 150 observations of aerial phenomena referred to above have been recorded in the vicinity of installations in New Mexico. A number of observations have been reported by different reliable individuals at approximately the same time. KWD / mp RECORDED - 2 INDEXED - 2
