Project 10073 Record Card and Related Correspondence: Hallett Station Sighting, 7 July 1962

This document contains records and correspondence regarding an unidentified aerial phenomenon observed at Hallett Station, Antarctica, on 7 July 1962. At 1115Z, witnesses, including the Scientific Leader and the Officer in Charge, observed an intense light that they initially mistook for a flare. The object was described as being as large as a basketball, accompanied by two smaller lights to its rear and sides, and leaving a white vapor trail. The object traveled from the west-south-west to the east-north-east. At an elevation of 7 to 10 degrees, the object produced a brilliant flash of light before disappearing at the horizon. Witnesses reported hearing whistling or rumbling sounds, similar to explosions. The report notes that the sighting was recorded on a sky camera and that the film was to be processed. The Foreign Technology Division (FTD) concluded that the object was likely a bolide (fireball). They also considered the possibility that the sighting was related to the re-entry of the U.S. satellite Alpha-Beta I, which decayed on the same date. The document also references a separate sighting on 22 June 1962, which was also attributed to a fireball, and a 7 June 1962 sighting, which was attributed to the misidentification of the planet Jupiter due to atmospheric distortion. The FTD stated there was no evidence of other foreign or domestic activities that could account for these phenomena.
