On August 27, 2012, at approximately 22:00 hours (10:00 PM), a motorist and passengers traveling through Montsalvy in the Cantal department of Auvergne, France, observed a rapidly moving white and green luminous phenomenon in the night sky. The witnesses were intrigued by the unusual coloration and movement pattern of the object as it traversed overhead.
Only one formal witness testimony was submitted to GEIPAN (France's official UAP investigation service under CNES), despite multiple people in the vehicle observing the phenomenon. The description provided was notably brief and lacked the level of detail typically required for comprehensive analysis. The witnesses described the phenomenon as having both white and green coloration and moving at very high speed across the sky.
GEIPAN investigators noted that the characteristics described—particularly the green color and rapid velocity—were consistent with a bolide (meteor/meteorite entering the atmosphere). However, despite GEIPAN's request for additional information from the witness, insufficient detail was provided to confirm this hypothesis with certainty. The case was ultimately classified as "C" (lack of consistency in testimony) due to the sparse nature of the available information.

04 Analyst Notes -- AI Processed
This case presents a common challenge in UAP investigation: insufficient witness cooperation and detail despite multiple observers. The fact that an automobile contained multiple witnesses but only one submitted a report suggests either passenger reluctance to come forward or the primary witness submitting on behalf of the group. The description's brevity is particularly notable given GEIPAN's follow-up request for more information, which apparently went unanswered or yielded insufficient additional data.
The green coloration is a significant detail that strongly supports the meteor hypothesis. Meteors frequently display green hues due to ionized oxygen and magnesium burning as the object enters Earth's atmosphere at hypersonic speeds. The reported rapid movement is also entirely consistent with meteor behavior. However, the inclusion of 'white' coloration and the description of 'movements' (plural) rather than a single trajectory might suggest something more complex than a simple meteor. Without trajectory data, duration estimates, angular size, or directional information, it's impossible to rule out other phenomena such as flares, drones with lighting, or conventional aircraft with unusual lighting configurations.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Misidentified Conventional Aircraft
The witness may have observed an aircraft with navigation lights appearing unusual due to viewing angle, atmospheric conditions, or distance. The 'green' light could be a starboard navigation light, while 'white' could be landing or strobe lights. The perceived rapid movement might be an illusion created by the vehicle's own motion combined with limited reference points in a dark rural sky.
06 Verdict
ANALYST VERDICT
The most likely explanation for this sighting is a meteor (bolide) entering Earth's atmosphere. The green coloration and high velocity are classic meteor characteristics, and the timing (late evening) is consistent with meteor observations when the sky is dark enough for such phenomena to be clearly visible. Confidence in this assessment is moderate (60-70%) due to the sparse witness testimony and lack of corroborating reports from the region. This case is significant primarily as an example of investigative limitations when witness cooperation is minimal, despite official investigation channels being available. The GEIPAN "C" classification is appropriate—the case lacks sufficient data for definitive conclusions but doesn't warrant continued active investigation given the probable natural explanation and absence of anomalous characteristics that would suggest something extraordinary.
