Vielle-Soubiran 1991, blue sphere with sparking trail

Summary

On August 20, 1991, at 5:30 AM, two gendarmes on patrol spotted a very bright bluish sphere traveling at high speed and leaving a trail of sparks. The observation was momentary and no other witnesses were found. The description points to an atmospheric entry, whether a meteorite or artificial debris. GEIPAN classified the case as B, considering a conventional explanation plausible without fully confirming it.
