Project 10073 Record Card and Air Intelligence Information Report - 2 September 1952

This document consists of a Project 10073 record card and an associated Air Intelligence Information Report regarding a sighting on 2 September 1952. At 2345 hours PDST, four civilian witnesses in Riverside, California, observed an unidentified aerial object. The object was described as star-like in appearance, displaying blue, red, and yellow colors. It was reported to move erratically, shifting left to right and up and down, with an estimated speed slower than a normal meteor. The object was located approximately nine miles north of March Air Force Base, positioned 45 degrees east of the North Star and 30 degrees above the horizon. The observation lasted for approximately three minutes. No exhaust trail was noted, and no observing instruments were available to the witnesses. The sky conditions were reported as clear and unlimited. A separate investigation report dated 21 October 1952, authored by S/A Arthur W. Watts, details a similar sighting over Los Alamos, New Mexico, on 3 September 1952. In that instance, witnesses from the Atomic Energy Commission reported a white light that varied in density from 'very dim' to 'near glaring.' This light approached from the East, stopped, and then proceeded South at an estimated speed of 200 to 300 miles per hour. The Los Alamos report notes that the light was observed by S-site employees for approximately three minutes. The report further mentions that a similar light appeared in the same area three minutes after the first disappeared, following the same procedure of appearance, stopping, and proceeding South. Both reports were processed through the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
