This document is a Project 10073 record card and associated teletype report concerning an unidentified aerial phenomenon observed on April 4, 1958, in Morro Bay, California. The witness, identified as S/SGT Cook of the 775th ACWRON, reported observing a single, round, silver object, described as being the size of a pinhead. The object was observed at an elevation of 70 degrees and an azimuth of 120 degrees. It reportedly moved slowly in a westerly direction before passing behind clouds, with a total observation time of eight minutes. The witness noted that there was no sound associated with the object. The report indicates that no radar contact was made, and no photographs were taken. The weather conditions were described as overcast with poor visibility. The official evaluation, provided by 1st Lieutenant Richard S. Garoppo, the Duty Director of ASO, concluded that the sighting was likely a star, a balloon, or a reflection off the ocean. The report explicitly states that there was insufficient data for a definitive evaluation, noting a lack of information regarding wind conditions and the specific time of the sighting.
