GEIPAN — Unidentified Aerospace Phenomena Study and Information Group (CNES)
Groupe d'études et d'informations sur les phénomènes aérospatiaux non identifiés
Component of CNES — Centre national d'études spatiales
The world's longest-running official civilian UAP investigation — inside the French space agency since 1977, publishing its case files since 2007.
No scorecard yet
Aletheca has not filed with this body, so there is nothing to measure. A zero here would read as “releases nothing” rather than “never asked”, which is why the row is absent instead of empty. Filing outside the United States is not yet supported, so for now this record is for reading and routing.
How it takes requests
- 01portalCase search and sighting questionnaireverified
https://www.cnes-geipan.fr
Routes marked verified were fetched and confirmed against the body’s own official pages; those marked unconfirmed are well documented but have not been checked here, and none has been proven by a delivered letter. Aletheca cannot yet originate a request outside the United States — this record exists so a request about these holdings can be routed to the right door.
What it holds
- The public case base — sightings since 1937, each classified A/B/C/D by residual strangeness after investigation
- Witness questionnaires, gendarmerie reports and analysis notes (anonymised)
- Predecessor files: GEPAN (1977–88) and SEPRA (1988–2004)
Record classes this kind of body normally keeps. Useful for drafting a request a records officer can act on without guessing — a request describing records the agency does not hold is refused as no-records, which costs a filing fee and teaches nobody anything.
Filing tips
- A formal request is usually unnecessary — GEIPAN publishes its case base proactively; search it before invoking the CRPA at all.
- For what is not published (raw witness identities, defence-classified material), the CADA route applies to CNES as to any French public body.
