Project 10073 Record Card: Sighting near SE Guam, 19 December 1960

On December 19, 1960, at 190921Z, the crew of the USS Havenfield observed an unidentified object near Southeast Guam at coordinates 11-41-0N, 147-04-0E. The object, described as having the magnitude of a first-magnitude star, was tracked for 19 minutes. It was initially sighted at 15 degrees elevation on a 335-degree bearing and followed a straight flight path, disappearing at 5 degrees elevation on a 130-degree heading. The weather conditions were reported as clear with clouds at 10 degrees on the horizon. No radar contact was established during the event. The Commanding Officer of the USS Havenfield believed the object to be a satellite. The report was processed under Project 10073 and submitted in accordance with AFR 200-2. The Air Technical Intelligence Center (ATIC) evaluated the report, noting that while the characteristics of a satellite were present, the identification remained unconfirmed. A request for additional information was issued by the military authorities, but no further response was received. The document includes both a Project 10073 record card and the original teletype message (DDO 37007) transmitted from the 3960th Combat Support Group at Andersen Air Force Base to Wright-Patterson Air Force Base and other military commands.
