At approximately zero four hundred twenty hours, an object was observed for a period of four minutes. The object was described as a glowing, bright light, appearing brilliant and moving slowly. The observer noted that the object first appeared to the east of the observer, then traveled northward, continued north for approximately two miles, then turned back south for approximately two miles, and finally resumed a northward course. The altitude of the object was estimated at one thousand feet, with a reported position of point one zero four three on the local grid. The observer, identified as Second Lieutenant, United States Air Force, stationed at Hamilton Air Force Base, California, recorded that the object was observed at ten thousand feet, traveling at one forty knots, and later at twenty thousand feet, traveling at one seventy knots. No sound was associated with the phenomenon. The report concludes that the unidentified object was most likely a weather balloon, although the bright, brilliant nature of the light and the lack of any visible balloon envelope were noted as unusual. Prepared by: 2d Lt., United States Air Force, Director of Intelligence, North Control, Chico, California. Captain, United States Air Force, Director of Intelligence, Wright‑Paterson Air Force Base, Ohio. End of Report.” The Black Vault’s editorial summary for this file states: “The report describes an unidentified aerial phenomenon observed over Chico, California on August second, nineteen fifty‑two, noted for its bright, brilliant light and lack of sound.” This statement is reproduced verbatim from the archive’s description.
