UFO sighted in Alpine Arizona in 1957

Summary

A civilian observer in Alpine, Arizona, reported in 1957 the presence of a round, white object the size of a nickel. The object was moving downward and shifted one degree west while remaining in sight. Although no photos were taken, the report details that the object was seen with the naked eye from the ground. The duration of the observation is not precisely stated, but it is mentioned that the object continued moving until it disappeared from view.

Investigators considered the possibility that the object was a balloon, an aircraft, or an astronomical phenomenon. An astrographic plot showed that Venus was in the southwest at the time of the sighting, but the observer did not specify the exact direction of the object. This created some ambiguity in the evaluation of the report. Ultimately, investigators concluded that the object could have been an astronomical phenomenon, though other possibilities were not ruled out.
