Mystery solved with an Iridium flare

Summary

On the evening of August 29, 2015, a French citizen observed a luminous phenomenon from his terrace while stargazing. The event was reported to the GEIPAN, with only one witness account. The observer described a stationary bright point, visible for about 10 seconds, with a brightness similar to that of a star. These characteristics are typical of an Iridium flare, a phenomenon caused by sunlight reflecting off Iridium satellites. By cross-referencing the witness data with astronomical records, it was confirmed that the event matched an Iridium 54 flare, reaching a maximum magnitude of -6.6. Due to this match, the GEIPAN classified the case as "A", meaning it was explained as an Iridium flare.
