UFO in Bas-Rhin 1980

Summary

On the night of April 11 to 12, 1980, several witnesses in Bas-Rhin observed a luminous phenomenon that generated great intrigue. This case, initially classified as D, was re-examined by the GEIPAN and is now considered explained. The witnesses reported a light that seemed to follow their vehicle, creating the illusion of a "following ball." However, after a detailed analysis, it was determined that the phenomenon was Venus, visible with a magnitude of -4.4. The duration of the observation, the low altitude in the sky, and the behavior of the object as it disappeared behind the local relief matched the known characteristics of Venus. Moreover, the testimonies of several witnesses, despite minor discrepancies, pointed to the same direction and position, reinforcing the identification.

The analysis also considered possible confusions caused by the low elevation of Venus and atmospheric layers, which can alter the perception of color and movement. Although one of the witnesses mentioned a supposed escape towards the northeast, this discrepancy was not confirmed by the other three witnesses and was considered a misperception. In summary, the case was resolved by identifying the phenomenon as Venus, and the GEIPAN classified it as case A, meaning explained. This re-evaluation shows how technical advances and accumulated experience allow for solving cases that initially seemed inexplicable.
