GEIPAN Case 2012-04-08222 — SAINT-LO (50) 04.04.2012

Brief

At 20:15 on April 4, 2012, a single civilian witness in Saint-Lô (Manche department, Normandy) observed two yellow or white luminous points traversing the sky from east to north at high speed. The first point maintained a straight, uniform trajectory; the second circled continuously around it — behavior the witness found captivating and that drove GEIPAN's D1 classification. D1 is GEIPAN's designation for observations that are both high-quality and genuinely unexplained, placing this among the more significant cases in the agency's public database. Attached materials reportedly include gendarmerie procès-verbaux, indicating a formal law-enforcement witness statement was collected.

Key points

• The case carries a D1 classification — GEIPAN's designation for observations that are high-quality and remain without conventional explanation.
• Two luminous points, described as yellow or white, were observed crossing the sky from east to north at significant speed.
• The second object executed continuous orbital motion around the first, which itself held a straight, uniform trajectory — the behavioral asymmetry between the two objects is the primary anomalous feature.
• The observation was made at 20:15 local time on Wednesday, April 4, 2012, placing it at or shortly after civil twilight — consistent with a witness being able to track luminous points against a darkening sky.
• Attached materials reportedly include gendarmerie procès-verbaux, placing the witness statement within the French law-enforcement record rather than relying solely on informal self-reporting.
• GEIPAN is the institutional successor to GEPAN and SEPRA, both earlier UAP investigation programs housed within CNES; this case carries the same legal and scientific standing as all prior filings in that lineage.

Most interesting

• The continuous orbital motion of the second object around the first is the single detail that elevates this above a routine lights-in-the-sky report; straight-line flight alone would likely have produced a lower classification.
• GEIPAN's D1 tier is comparatively rare in the public database — most cases resolve to category A (explained) or C (insufficient data to classify).
• The listed release date of 2007-03-22 predates the incident by nearly five years, suggesting it marks when GEIPAN's public database was formally opened rather than when this specific case was added.
• Saint-Lô is the prefecture of the Manche department in Normandy and has no documented UAP cluster in the GEIPAN record, making this an isolated civilian report rather than part of a regional wave.
• France is one of the few countries with a permanent, government-funded UAP investigation body that publishes case files publicly; GEIPAN's mandate under CNES gives this filing an institutional weight absent from most national UAP records.
• The observation duration is not specified in the description, but the witness's sustained focus on the second object's orbital pattern implies the event lasted long enough for that motion to be characterized — ruling out a brief ambiguous flash.
