Project 10073 Record — Incident 414, Point Barrow, Alaska

On July 27, 1949, personnel at a weather station in Point Barrow, Alaska, observed an unidentified light in the sky while engaged in tracking a weather balloon. The object was tracked for approximately six hours, during which time it maintained a level flight path from East to West at an estimated speed of 3 to 4 degrees per minute. The observers utilized a 20-power theodolite to monitor the object, which was estimated to be at an altitude between 50,000 and 60,000 feet. The incident was formally recorded as Incident 414 under Project 10073. Following the report, an astronomer named Dr. Sinley, who was present at Point Barrow and affiliated with the Office of Naval Research (ONR), provided an expert opinion that the light was definitely a planet, suggesting it was likely Venus. The Air Materiel Command (AMC) later reviewed the data and plotted the object as Jupiter. The documentation includes internal military correspondence requesting a detailed report from the witnesses and the original incoming message regarding the sighting. The report confirms that no physical evidence or photographs were obtained during the observation.
