GEIPAN (an acronym in French forGroupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non-identifiés, or Unidentified Aerospace Phenomenon Research and Information Group) (/ɡaɪˈpɑːn/) is a unit of the French space agencyCNES based inToulouse, whose brief is to investigate unidentified aerospace phenomena (UAP)[1] and make its findings available to the public.
GEIPAN was founded in 1977 asGEPAN (Groupe d'Étude des Phénomènes Aérospatiaux Non-identifiés, Study Group for Unidentified Aerospace Phenomena). Claude Poher was the inaugural director,under the permission[clarify] of then director general of CNESYves Sillard.
GEPAN was renamed toSEPRA (Service d'Expertise des Phénomènes de Rentrée Atmosphérique, Atmospheric Re-entry Phenomena Expertise Department) in 1988,[2] and then toService d'Expertise des Phénomènes Rares Aérospatiaux ("rare aerospace phenomena expertise department") in 2000.[citation needed] In 2005, the research unit was renamed to GEIPAN.[2]
The FrenchGendarmerie was instructed to channel data from reports ofUFO sightings to SEPRA, which therefore was in a position to draw on a large database of such events. In cases where physical traces appeared to be present, SEPRA could call on the technical resources ofCNES to perform a thorough scientific investigation. A famous example of such an investigation was theTrans-en-Provence Case.

In March 2007, GEIPAN started to make itsarchives available online to the public. The same year, French skeptics criticized the quality of their investigative work, arguing the sightings were too quickly filed as unidentified.[3] On March 26, 2007, the CNES' own report said that 28% of sightings remain unidentified.[4]
More recent reports of GEIPAN estimate the unidentified sightings at around 3%.[5][6]
