Project 10073 Record Card — Seattle, Washington, 3 January 1950

This document is a Project 10073 record card detailing an unidentified aerial phenomenon sighting that occurred on January 3, 1950, in Seattle, Washington. The report describes a single, circular, reddish-orange object, estimated to be the size of a grapefruit, which featured a bright center surrounded by a hazy circle. The witness, identified as a civilian, observed the object hovering in the western sky for approximately three to four minutes before it spread out and disappeared. The report includes a teletype communication (RJWZDM 35E) which provides additional technical details, noting that the object was observed at an altitude of approximately three degrees above the horizon and exhibited a west-to-east oscillation. The official conclusion reached by the investigating authorities was that the object was likely a reflection from a fog bank or a passing cloud. Further comments suggest that the reported brilliance might have been caused by ground lights reflecting off rising smoke, steam, or the base of a cloud. The document also notes that meteors were observed by the Seattle ARTCC Watch Supervisor at 7:57, though this appears to be a separate observation. The report follows the standard format for Project 10073, referencing Air Force Regulation 20-2, and includes administrative data regarding the sighting's characteristics and the lack of radar or photographic evidence.
