Montfort-sur-Meu 1987, UFO sighting classified as A

Summary

In November 1987, several witnesses in Montfort-sur-Meu (France) reported a bright red object moving slowly or remaining stationary towards the west. Descriptions varied between a ball and a banana-like shape, and no sound was heard. The gendarmerie investigated and found no suspicious traces or aerial activity in the area. Initially classified as D (unexplained), the GEIPAN re-examined the case using new tools and experience. Astronomical data showed that the Moon was in a first quarter phase and in a similar direction to the observation, explaining the object's appearance. Despite witnesses insisting it wasn't the Moon, the data matched perfectly with its position and look. The re-evaluation concluded it was a misinterpretation of the celestial body, leading to a classification of A.
