On November 12, 2008, at approximately 22:40 (10:40 PM), a motorist driving near Carspach in the Haut-Rhin department of Alsace observed a striking green light descending in a curved trajectory across the night sky. The phenomenon was accompanied by a cone-shaped trail and lasted only a few seconds. The witness's account was remarkably consistent and quickly drew attention when similar reports emerged from other locations.
The sighting was independently corroborated by two additional witnesses located in the Bordeaux region, approximately 700 kilometers away. These distant observations, combined with the witness testimonies sharing compatible timing, descriptions, and trajectory data, immediately indicated the object was at extremely high altitude. A radio recording potentially captured contemporaneous discussion of the event. The geographic separation between Carspach in eastern France and Bordeaux on the Atlantic coast provided crucial triangulation data that helped investigators determine the phenomenon's altitude and nature.
GEIPAN's investigation revealed this observation occurred during the peak activity period of the Northern Taurid meteor shower, known for producing spectacular, slow-moving fireballs. The date, time, description of the green luminosity, cone-shaped trail, and curved descent path all matched the characteristic signatures of a meteoroid atmospheric entry. The witness himself suspected a meteor after conducting personal research, and GEIPAN's thorough analysis confirmed this hypothesis, classifying the case as 'A' - a fully explained phenomenon with high confidence.

04 Analyst Notes -- AI Processed
This case demonstrates excellent investigative methodology by GEIPAN and represents a textbook example of meteor identification. The 'A' classification (highest certainty of explanation) is well-supported by multiple corroborating factors: independent witness reports separated by significant distance, timing coinciding with known meteor shower peak activity, and physical characteristics consistent with bolide behavior. The green coloration is typical of meteors containing magnesium and other elements burning during atmospheric entry.
The credibility assessment is strengthened by the discovery of independent witnesses through forum searches and the consistency across geographically separated observations. The distance between Carspach and Bordeaux (approximately 700km) provides compelling geometric proof that the object was at very high altitude, eliminating possibilities of local aircraft, drones, or atmospheric phenomena. The Northern Taurids are well-documented for producing bright, slow fireballs during their November peak, and the witness's own research instincts were correct. The mention of a potential radio recording adds an interesting dimension, though details are not elaborated in the available documentation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Initial Misidentification Concerns
Before correlation with distant witnesses, this could theoretically have been misidentified as local atmospheric phenomena, aircraft with unusual lighting, or even pyrotechnic activity. However, the geographic separation of independent witnesses, timing precision, and characteristic meteor signature eliminate all alternative explanations. The skeptical position acknowledges that single-witness meteor reports can sometimes be ambiguous, but this case provides exceptional corroboration.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a meteoroid from the Northern Taurid meteor shower entering Earth's atmosphere. The GEIPAN 'A' classification is entirely appropriate and reflects high investigative confidence. The convergence of evidence - precise timing during peak shower activity, characteristic green luminosity and cone-shaped trail, multiple independent witnesses across vast distances, and physical behavior matching known bolide signatures - leaves no reasonable doubt. While visually spectacular and initially puzzling to witnesses, this represents a natural astronomical phenomenon rather than anything anomalous. The case's value lies in demonstrating how proper investigation methodology, witness correlation, and astronomical knowledge can efficiently resolve apparently mysterious sightings.
