Project 10073 Record Card — Aberdeen Proving Ground, Maryland, 6 July 1957

On July 6, 1957, at 0220Z, a military witness at the Aberdeen Proving Ground in Maryland reported a sighting of an unidentified object. The witness described the object as appearing yellow with a halo around its top, noting that it changed in size from small to large. The object was observed for a duration of three hours, during which it maintained a high altitude and performed a slow, tight circular turn. The weather conditions at the time were reported as clear and calm. The sighting was documented on a Project 10073 record card. Although the initial report indicated that the specific object could not be identified, the final conclusion reached by the evaluating agency was that the object was an astronomical star. The report includes a remark that the witness claimed to have seen three or more such objects previously, though this was the first instance he had formally reported. The documentation includes a teletype message confirming the details of the sighting, including the geographic coordinates of 39:27 N - 76:25 W, and notes that the witness was a member of the U.S. Army.
