Groupe d'Études des Phénomènes Aérospatieux Non Indentifiés (GEPAN)

Groupe d'Etudes des Phénomènes Aérospatieux Non Indentifiés (French: Study Group for Unidentified Aerospace Phenomena) was a department of the Centre National d'Études Spatiales (CNES), the French space agency, based in Toulouse and active from 1977 through 1988, which was given the task of investigating "unidentified aerospace phenomena" and issuing public reports on their findings. It was succeeded in 1988 by the Service d'Expertise des Phénomènes de Rentrées Atmosphériques (SEPRA).
