OTTMARSHEIM 1980 reddish phenomenon in the sky

Summary

On March 4, 1980, around 9:45 PM, several witnesses in Ottmarsheim (France) observed a luminous phenomenon five times larger and brighter than a star. The ball appeared reddish-orange and remained stationary in the sky. Although unusual in appearance, the investigation concluded that atmospheric conditions were ideal for observing planets like Mars with a particular aspect.

This case was classified as "B" by the GEIPAN, meaning no conventional explanation was found, but it was not considered unexplained either. The witnesses' descriptions and weather conditions matched the view of Mars during a period of intense brightness.
