Confused lunar observation with UFO

Summary

A case classified as "A" by the GEIPAN in France shows how a family observed a luminous object in the shape of a half-sphere in a cloudy sky on January 27, 1982. The object made no noise and moved slowly, causing confusion. Two witnesses returned to the location but the object was gone. The investigation concluded that what was observed was actually the setting Moon, misidentified due to its tilted shape and cloud cover. The Moon was precisely in the witnesses' field of view, but it was not recognized due to its low elevation and lighting. The description provided by the witnesses, including the object's movement relative to their vehicle, matches the apparent trajectory of the Moon. The disappearance of the "object" is explained by the Moon setting or a change in cloud cover.
