Venus mistaken for a UFO in Toulaud

Summary

During a nighttime military exercise in May 1980, French soldiers in Ardèche observed a bright, silent point of light that seemed to approach and recede unpredictably for over an hour. Despite their training, the witnesses could not identify it as a known celestial body.

A later review by GEIPAN, using modern analytical tools, determined the object was Venus. Its low position on the horizon combined with atmospheric refraction effects created the illusion of movement and fluctuating brightness. Originally classified as D, the case was downgraded to category A — a textbook example of how even experienced observers can mistake a planet for an anomalous phenomenon under certain atmospheric conditions.
