Project 10073 Record: Incident 382 — Los Alamos, New Mexico, 2 June 1949

This document is a Project 10073 record detailing an unidentified aerial phenomenon sighting that occurred on June 2, 1949, at 0040 LST in Los Alamos, New Mexico. The witness, identified as a security inspector for AESS, observed a single green 'ball of light' while in an automobile. The object was described as self-luminous, leaving a long, unbroken green trail of the same width as the object itself. The object was observed for approximately one second as it descended at a 40-degree angle from the East toward the North. The estimated altitude of the object was between 7,000 and 10,000 feet, and it appeared to be approximately five miles from the observer. The weather conditions at the time of the sighting were reported as clear. The observer reported no sound or odor associated with the object. The investigation into the incident included a review of the observer's background, which was conducted under PL 585, confirming that the individual met the requirements for employment with AESS. The official conclusion reached by the project investigators was that the object was an 'Astro (METEOR)'. The report includes multiple standardized forms used for the investigation of unidentified aerial objects, documenting the specific characteristics of the sighting and the administrative processing of the report.
