Project 10073 Record Card — Oklahoma City, Oklahoma, 9 January 1959

On January 9, 1959, an electronic technician working at a refinery in Oklahoma City, Oklahoma, reported observing an unidentified object while at Will Rogers Field. The witness, who was using a welding helmet with a size nine filter to examine the sun, described seeing a round, dark object with protrusions that appeared to be the size of a pinhead at arm's length. The object exhibited slow spiraling motions and moved from left to right across the sun. The observation lasted from sunrise to sunset. The witness took two photographs of the phenomenon. Military intelligence, specifically the 746th ACWRON, processed the report under Project 10073. The official conclusion reached by the Air Technical Intelligence Center was that the object was an astronomical sunspot. This determination was based on the fact that the spots were only visible through the welding filter while looking directly at the sun and were no longer observable after sunset, leading investigators to conclude that the witness had observed sunspots rather than an anomalous aerial vehicle.
