Summary

Between 9:15 and 9:30 PM on December 6, 1979, several people in Plancoët (Côtes-d'Armor) first observed a white luminous mass moving from west to east, then five orange light sources whose shape varied by witness — streaks or ovals. They gradually faded out toward the east. No further testimonies were collected. GEIPAN classified the case as C, unable to reach a satisfactory explanation.
