Project 10073 Record Card — Warrensville Heights, Ohio, 10 May 1964

On May 10, 1964, two witnesses in Warrensville Heights, Ohio, observed an unidentified object in the southeastern sky while stargazing. The object, which appeared white and gradually turned light green, was observed through a 36X telescope, where it initially appeared rectangular—a feature the witnesses later attributed to improper telescope focus. To the naked eye, the object appeared as a star of second magnitude. The witnesses timed the object's transit across the sky at four minutes and fifty-seven seconds, noting its disappearance at 35 degrees of elevation. Following their report to the Air Technical Intelligence Center at Wright-Patterson Air Force Base, the Foreign Technology Division investigated the incident. Official correspondence from the Foreign Technology Division and the Public Information Division confirmed that the object sighted by the witnesses was the ECHO I satellite, which was positioned to the south of the city at a 12-degree elevation and moving northeast at the time of the sighting.
