Project 10073 Record Card — Ellsworth AFB, South Dakota, September 1958

This document is a Project 10073 record card and associated teletype communication regarding an Unidentified Aerial Phenomena (UAP) sighting reported on September 8, 1958, at Ellsworth Air Force Base, South Dakota. The sighting occurred at 0305Z and involved a single, stationary object described as a pin-point-sized light that flashed red, white, and green. The object was observed by two United States Air Force officers, Lieutenant Dwyer of the 54th FIS and Second Lieutenant Margus F. Roggenbuck. The witnesses noted that the object was very high in the sky and remained visible for at least two hours. The report indicates that the sky conditions were clear at the time of the observation. The teletype communication, originating from the Commander of the 740th ACWRON, was directed to the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base, among other commands. The official evaluation conducted by ATIC concluded that the object was likely the star Arcturus. This conclusion was based on the object's appearance, its stationary nature, and the absence of other planets or stars of the first magnitude in that specific vicinity. An investigator's note appended to the report highlights that the initial information provided was very limited, specifically noting a lack of precise elevation and azimuth data.
