Project 10073 Record Card: Sighting at Seaside Park, N.J., March 1958

This document contains a series of reports and correspondence regarding a UFO sighting in Seaside Park, New Jersey, occurring on March 21-22, 1958. The primary report, filed under Project 10073, details an observation by local police officers, including Patrolman J. Castor, of an elliptical, white-to-yellow object described as being the size of a large grapefruit. The object was observed for 3-4 minutes moving slowly from over the water toward land. The 539th Fighter Interceptor Squadron investigated the incident, noting that the observer was considered reliable, but suggested the object might have been a Navy P2V Neptune aircraft or a jet in afterburner. However, subsequent analysis by J. Allen Hynek of the Smithsonian Institution Astrophysical Observatory strongly suggested an astronomical explanation. Hynek's correspondence with Captain George T. Gregory at the Air Technical Intelligence Center indicates that the star Vega and the planet Venus were in the positions reported by the observers at the time of the sightings. Hynek expressed skepticism regarding the 'hostile' nature of such sightings, noting that the star Vega has been in that position for centuries and that people often misidentify celestial bodies. The document also includes a separate, brief mention of a 'daylight meteor' sighting, which Hynek suggests could have been a burst weather balloon or an aircraft reflection, concluding that there was insufficient data to distinguish it from other phenomena. The overall conclusion of the military and scientific review was that the sightings were likely astronomical in nature, specifically misidentifications of bright stars or planets, and that no hostile activity was involved.
