Sighting in Saint-Rémy-lès-Chevreuse, March 9, 2014

At around 7:50 pm, a witness at home watched a faintly luminous phenomenon cross the sky in a straight line over two to three seconds. It looked like a glowing ball and left a long white trail behind it.

GEIPAN considered that these features match those of a bolide (a fireball). The BOAM amateur network of automatic cameras recorded nothing at that time, possibly because the phenomenon was not bright enough. Two bolides were, however, captured that same evening by cameras in eastern France, at 9:03 pm and 11:28 pm. GEIPAN also received a firsthand account from someone who had seen a phenomenon near Bordeaux between 7:30 and 7:45 pm the same day. The directions of travel are compatible, but the reported times do not match exactly.

Without further confirmation, the case was classified B: probable observation of a bolide. Bolide sightings are, moreover, numerous in February and March.
