White UFO sighted in Mira Loma in 1955

Summary

In July 1955, a witness in Mira Loma, California, reported a bright object that appeared suddenly and disappeared after about 45 seconds. It was described as a round, white object the size of a silver dollar, moving in a horizontal path. Although initially considered a meteor, military authorities suggested the possibility of optical phenomena due to weather conditions like a temperature inversion and the moon's position. The official report concluded there was insufficient evidence to determine the object's nature definitively, ruling out conventional explanations like balloons or aircraft.

The case was part of a broader investigation into sightings in the area, with astronomers and meteorologists consulted for more data. Despite efforts, no other similar sightings or scientific explanations were confirmed. This document reflects the uncertainty surrounding many UFO reports at the time, as authorities tried to balance assessing potential threats with a lack of solid evidence.
