Project 10073 Record Card — Ann Arbor, Michigan, 23 February 1958

This document is a Project 10073 record card detailing a UFO sighting reported by a civilian in Ann Arbor, Michigan, on February 23, 1958. The witness observed a single, round object, estimated to be 6 to 8 inches in diameter, which appeared silver and gold and reflected light. The object was described as looking like a 'low moon' and moved from a 60-degree to a 180-degree azimuth over a duration of five seconds, traveling from the West-Northwest to the East-Southeast. The observation occurred at dawn, under clear and crisp sky conditions. The witness reported the object was 63 degrees above the horizon. The report includes a teletype message confirming the submission of the UFO report in accordance with Air Force Regulation 228-2. The official conclusion reached by the investigating authorities was that the object was a meteor. The rationale provided for this classification was that the speed and distance traveled were consistent with meteor activity, and the ambient lighting conditions at dawn were sufficient for the object to appear as a reflecting light source. The document also notes that the object appeared as a metal sphere made of white metal, though this is superseded by the final classification as a meteor observation.
