PROJECT 10073 RECORD CARD - 10 MAR 58

This document is a Project 10073 record card detailing a civilian sighting of an unidentified object on March 10, 1958, near Alsea, Oregon. The witness reported observing a single object, described as being the size of a grapefruit, which twinkled, glittered, and emitted a flashing light. The object was observed for approximately 30 minutes, moving slowly in a southerly direction. The weather conditions were reported as clear with 30 miles of visibility. Following an investigation, the Air Technical Intelligence Center (ATIC) concluded that the sighting was likely a reflection of a flashing marine light located southwest of the observer's position, potentially caused by an atmospheric inversion or haze layer. The report notes that wind information and the duration of the sighting helped rule out the possibility of a balloon or aircraft. The document includes handwritten notes and a diagram illustrating the wind direction and the location of the light relative to the observer.
