Project 10073 Record Card — Brownville, Maine, 28 September 1955

This document is a Project 10073 record card and associated military teletype communication regarding a UFO sighting reported on September 28, 1955, approximately 30 miles northwest of Brownville, Maine. The report describes a single, round object that changed colors from red to green to yellow. The witness, identified as a civilian, observed the object for approximately two hours, noting that it made no sound and exhibited a movement pattern of dropping and rising. The object was described as being about the size of a jet aircraft. The military investigation involved the 765th ACWRON at Charleston AFS, Maine, and included coordination with the Air Technical Intelligence Center at Wright-Patterson AFB. Despite the report, no radar contact was established, and an interceptor sent to investigate was unable to locate anything, eventually returning to base due to fuel status. Weather conditions at the time were reported as clear with good visibility and no cloud cover. The official conclusion reached by the evaluating agency was that the object was the star Arcturus, noting that the star sets at 2230 at 300 degrees azimuth.
