On November 18, 2012, at approximately 20:30 hours, a witness in Douarnenez, Finistère, observed a stationary luminous phenomenon in the night sky using both naked eye and binoculars. The light exhibited green and red scintillations, had a dark center, and showed varying luminous intensity. The witness, sufficiently concerned by the observation, showed the phenomenon to several acquaintances before contacting the gendarmerie. A police patrol was dispatched to the location and independently confirmed the phenomenon's presence.
The gendarmes escalated the report to the Centre en route de la navigation aérienne Ouest (CRNA-O) near Brest. Air traffic controllers conducted checks and reported that an aircraft crew approaching Quimper and the controllers themselves observed nothing unusual that evening. Military forces were confirmed not to be operating in the sector, and primary radars at Lanvéoc and Landivisiau detected no anomalous activity. Despite a neighborhood canvass, only the single witness testimony was obtained. The phenomenon was observed for an extended period in the southeastern direction of the sky.
Weather conditions that evening included light westerly winds and very humid atmospheric conditions conducive to scintillation effects. While no bright celestial body was present in the southeast direction of observation, planet Jupiter was noted directly east. The CRNA report provided additional elements including the phenomenon's height above the horizon and confirmed the absence of visual or radar detection by aircraft crews and military radar installations. GEIPAN classified this case as 'B' - probable confusion with a Civil Security helicopter on a VFR (Visual Flight Rules) mission near Quimper Pluguffan airport, corresponding to the azimuth of the observation.
02 Timeline of Events

Initial Detection
Primary witness observes a stationary light in the sky with naked eye, then confirms with binoculars. Light shows green and red scintillations, dark center, and varying intensity.
20:30-20:45 (estimated)
Witness Gathers Corroboration
Witness moves to show the phenomenon to several other people in the vicinity before deciding to contact authorities.
~20:45-21:00 (estimated)
Gendarmerie Dispatched
Witness contacts gendarmerie. A patrol is sent to the location and officers independently observe and confirm the phenomenon.
~21:00-21:30 (estimated)
CRNA-O Alert and Investigation
Gendarmes alert the Centre en route de la navigation aérienne Ouest (CRNA-O) near Brest. Air traffic controllers begin checking radar data and contacting aircraft in the area.

Investigation conclusion
GEIPAN Classification
After analyzing witness testimony, gendarmerie reports, CRNA-O data, radar records from Lanvéoc and Landivisiau, and atmospheric conditions, GEIPAN classifies the case as 'B' - probable Civil Security helicopter.

04 Analyst Notes -- AI Processed
This case demonstrates a textbook example of aircraft misidentification under specific atmospheric conditions. The witness credibility is enhanced by the fact that local gendarmerie also observed the phenomenon, providing official corroboration. However, the investigation reveals several factors pointing toward a conventional explanation. The green and red scintillations are consistent with aircraft navigation lights (green starboard, red port), while the dark center could represent the aircraft fuselage silhouetted against the sky. The stationary appearance is typical of helicopters in hover or slow approach, especially when observed at distance.
The thoroughness of the official investigation is noteworthy - coordination between gendarmerie, CRNA-O air traffic control, and GEIPAN demonstrates proper protocol. The radar checks at Lanvéoc and Landivisiau, combined with confirmation of no military activity, effectively ruled out classified operations. The atmospheric conditions (humid air, light wind) would create ideal circumstances for scintillation effects, potentially enhancing the color changes and making the light appear more anomalous than it actually was. The single witness (despite others seeing it briefly) and lack of photographic evidence limit the evidentiary value. GEIPAN's assessment that the testimony was 'too concise, imprecise, and lacking essential data' is accurate.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Astronomical Object with Atmospheric Distortion
Initially considered was the possibility of a bright celestial body affected by atmospheric scintillation. Planet Jupiter was noted directly east at the time. However, this theory was ruled out because no bright astronomical object was present in the southeast direction where the witness observed the phenomenon. The stationary nature initially suggested a star or planet, but the directional mismatch eliminated this explanation.
Testimony Quality Concerns
The single-witness nature of the report, combined with GEIPAN's assessment that the testimony was 'too concise, imprecise, and lacking essential data,' suggests potential observer error or misperception. Despite brief corroboration by acquaintances and gendarmes, no detailed second witness account or photographic evidence exists. The low consistency rating indicates this could be a case where a mundane phenomenon appeared unusual due to unfamiliarity with the observer's part.
06 Verdict
ANALYST VERDICT
This case is most likely a misidentification of a Civil Security helicopter on approach to Quimper Pluguffan airport. Confidence level: High (80-85%). The combination of red and green navigation lights, stationary/slow movement pattern, location corresponding to known flight paths, and atmospheric conditions creating enhanced scintillation all point conclusively to a helicopter. The official classification as 'B' by GEIPAN is appropriate. What makes this case notable is not the phenomenon itself, but rather the exemplary investigation protocol - demonstrating how proper coordination between civilian witnesses, law enforcement, air traffic control, and scientific investigators can effectively resolve ambiguous sightings. The case serves as a useful reference for distinguishing atmospheric/optical enhancement of conventional aircraft from truly anomalous phenomena.
