Ottmarsheim, reddish sphere consistent with Mars

Summary

At around 21:45 on 4 March 1980, several witnesses in Ottmarsheim saw a fixed reddish-orange sphere in the sky, roughly five times larger and brighter than a star. The investigation found that atmospheric conditions were ideal for Mars to take on a particularly striking appearance. GEIPAN classified the case as B: no confirmed conventional explanation, yet not deemed a truly inexplicable phenomenon.
