Sighting in Mison, September 10, 2012

At about 10:25 p.m., a witness briefly saw a very bright white light with an orange tinge in the sky. The intense light then went out abruptly. The witness heard no sound. This was the only account collected about the event.

The investigation relied on several objective elements set out in the case report: an observation lasting roughly 20 seconds, which fits the duration of satellite flashes; the look of a very bright flash; an elongated shape moving slowly in a horizontal direction; and a position in the sky, both in azimuth and in elevation, that matched the satellite "ISIS 1", which was visible at that date and time.

GEIPAN concluded that the witness had probably seen a flash from this satellite as it emerged from the Earth's shadow cone. The case was classed B. Some uncertainty remains, however, about which satellite exactly produced the phenomenon.
