GEIPAN Case 2012-04-08222 — SAINT-LO (50) 04.04.2012
Single-witness GEIPAN case D1 (unexplained) from Saint-Lô, April 4, 2012: two luminous points crossed the sky east-to-north, one on a straight trajectory while the second continuously orbited the first.
Brief
On the evening of April 4, 2012, at 20h15, a witness in Saint-Lô (Manche, Normandy) observed two yellow or white luminous points moving rapidly across the sky from east to north. The first point held a straight, uniform trajectory; the second continuously maneuvered around the first, capturing the witness's sustained attention. GEIPAN, the French national space agency CNES's UAP unit, investigated with attached gendarmerie procès-verbaux and technical notes, ultimately assigning classification D1: the phenomenon remains unexplained after full analysis.

Key points
- Two luminous points, yellow or white, observed moving rapidly from east to north over Saint-Lô on April 4, 2012 at 20h15 local time.
- The first object maintained a straight, uniform trajectory; the second continuously orbited or maneuvered around it throughout the observation.
- GEIPAN assigned classification D1, the highest unexplained tier in the French system, indicating no conventional explanation was found after full investigation.
- Attached case materials include gendarmerie procès-verbaux and/or technical notes, confirming formal law-enforcement witness documentation.
- The case was handled by GEIPAN, successor to GEPAN and SEPRA within CNES, one of the world's longest-running official government UAP investigation units.
Most interesting
- GEIPAN's D1 classification is reserved for cases that remain genuinely unexplained after full investigation; it is not a default or catch-all category.
- The second object's behavior, continuously orbiting a moving primary object at high speed, is inconsistent with known aircraft, balloon, satellite, or drone flight profiles.
- Saint-Lô is in the Manche department of Normandy, with no notable restricted military airspace that would account for unconventional flight behavior in the area.
- The release date listed in the war.gov metadata (2007-03-22) predates the 2012 incident by five years, suggesting that date refers to the questionnaire form version, the database entry framework, or a cataloguing artifact rather than the document's actual release.
- France's GEPAN/SEPRA/GEIPAN lineage has operated continuously since 1977, making it the oldest institutionalized government UAP investigation program still active at the time of this case.
