Bright blue sphere seen by gendarmes

Summary

On August 20, 1991, at around 5:30 AM, two gendarmes on patrol briefly observed a very bright blue sphere moving at high speed with a trail of sparks. The object was only seen for a short moment, and no other witnesses could be found. Despite the lack of additional evidence, the described phenomenon resembles a natural or artificial atmospheric entry. The case was classified as "B" by the GEIPAN, indicating that a conventional explanation was not ruled out, but the possibility of an unusual phenomenon was not dismissed either.
