Two fixed luminous points in the sky over Bois-Guillaume

Summary

On November 7, 2008, a witness in Bois-Guillaume noticed two fixed luminous points in the eastern sky while waiting for their partner. Both objects slowly faded out. GEIPAN suggested they could have been two high-altitude weather balloons still illuminated by the sun roughly an hour after sunset, which would explain their bright, stationary appearance. However, this hypothesis could not be confirmed due to the time elapsed since the observation. The case was classified as B—a plausible but unverified explanation.
