Project 10073 Record Card — Lynbrook, New York, 10 December 1960

This document contains a sighting report and subsequent correspondence regarding an unidentified aerial phenomenon observed on December 10, 1960, in Lynbrook, Long Island, New York. The primary witness, a 67-year-old female, reported that she and her husband observed a large, round, flame-colored object in the sky at approximately 5:30 P.M. The witness described the object as appearing similar to a full, newly risen harvest moon. It remained stationary, then flared out, grew larger, and eventually disappeared. Later, the object reappeared further to the East before finally vanishing. The witness noted that the object did not seem to be the moon or an airplane. The Air Force responded to the witness's initial letter on February 27, 1961, requesting that she complete a formal Air Force questionnaire to provide more detailed information for analysis. The completed questionnaire, included in the file, provides additional context, noting that the witness was in her driveway when the object was spotted. The official conclusion recorded on the Project 10073 record card categorizes the sighting as a 'probable reflection.' The investigator's comments suggest that the object was likely a low-hanging cloud reflecting lights from the ground, which appeared to move or change due to the cloud's slow drift with the prevailing westerly winds. The file includes the original correspondence from the witness, the Air Force's request for further information, the completed technical information sheet, and the final evaluation by the Aerospace Technical Intelligence Center.
