GEIPAN Archive and Annual Statistics Summary

GEIPAN, a unit of CNES, collects reports primarily via the public, gendarmerie, and aviation authorities, applies a standardized seven-step scientific investigation process involving field work when warranted, and classifies outcomes transparently. The document details reproducible methodology based on current scientific knowledge, anonymization protocols, and public dissemination of results. It emphasizes that unexplained (D-category) cases represent a small minority and do not indicate extraterrestrial activity or advanced technology beyond known explanations; they simply lack enough information or exhibit characteristics not fully matched to current understanding. The archive of investigated cases is made publicly available on the GEIPAN website to promote transparency and further study.
