On December 13, 2012, at 16:48 UTC (5:48 PM local time), a commercial airline pilot operating in the vicinity of Toulouse, France, observed a striking green luminous phenomenon traveling from east to west. The witness, identified in GEIPAN records as affiliated with Ryanair (AERO RYR), was airborne at the time of the observation and estimated the object's altitude between 45,000 and 60,000 feet—significantly above typical commercial flight levels. The phenomenon was described as moving across the pilot's field of view in the 030° bearing relative to Toulouse, exhibiting the characteristic green coloration often associated with metallic composition in atmospheric entry events.
The timing of this sighting coincided precisely with the peak activity period of the Geminid meteor shower, one of the most reliable and prolific annual meteor events. The Geminids, which radiate from the constellation Gemini in the northeastern sky, were particularly active on December 12-13, 2012, with numerous observations recorded by automated camera networks and amateur astronomers across Europe. The east-to-west trajectory reported by the pilot is consistent with a meteor track, though the radiant point for Geminids would typically suggest a northeastern origin at that hour.
Despite the widespread Geminid activity during this period, GEIPAN received no corroborating reports for this specific event at 16:48 UTC. The French space agency classified this case as "B"—probable identification with high confidence—concluding that the witness observed a meteoroid entering Earth's atmosphere. The green color indicates the presence of nickel, magnesium, or copper in the meteoroid's composition, a common characteristic of meteoric material burning up during atmospheric entry at hypersonic speeds.

04 Analyst Notes -- AI Processed
This case presents a textbook example of a credible witness observing a natural astronomical phenomenon under ideal conditions. The witness credibility is exceptionally high: a commercial airline pilot trained in aerial observation, familiar with atmospheric phenomena, and positioned at altitude with unobstructed visibility. The pilot's ability to estimate altitude (45,000-60,000 ft) and provide precise bearing (030° from Toulouse) demonstrates professional observational skills. The green coloration is a diagnostic signature of meteoric entry, caused by metal emission lines as the object ablates in the upper atmosphere.
The temporal correlation with the Geminid meteor shower peak provides strong contextual support for the meteoroid hypothesis. However, one analytical anomaly warrants note: the reported east-to-west trajectory is not perfectly aligned with typical Geminid radiant geometry, which would suggest more northeasterly origin vectors at 16:48 UTC. This could indicate either a sporadic (non-Geminid) meteor, slight observational error in trajectory estimation, or perspective effects from the pilot's moving aircraft. The altitude estimate of 45,000-60,000 feet is consistent with the luminous phase of meteor ablation, though actual meteoroid disintegration typically occurs between 50-80 km (approximately 164,000-262,000 feet). The pilot may have been estimating apparent altitude rather than actual altitude. The absence of corroborating witnesses is not unusual for daytime fireballs, which are far less conspicuous than nocturnal meteors and often go unreported except by trained observers or those specifically watching the sky.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Altitude Estimation Uncertainty
The pilot's altitude estimate of 45,000-60,000 feet may be significantly underestimated. Meteors typically become luminous between 50-80 km altitude (164,000-262,000 feet) and burn out by 30-40 km. Visual altitude estimation of objects against empty sky is notoriously difficult, even for trained pilots. The witness may have been providing apparent altitude or making an unconscious comparison to familiar flight levels rather than actual slant range calculation.
06 Verdict
ANALYST VERDICT
This case is almost certainly a confirmed observation of a bright meteor (fireball-class bolide) entering Earth's atmosphere during the 2012 Geminid meteor shower peak. Confidence level: very high (approximately 95%). The combination of factors—professional pilot witness, green coloration diagnostic of metallic composition, temporal coincidence with peak Geminid activity, appropriate altitude range, and brief duration—all support a meteoroid explanation with minimal ambiguity. The GEIPAN "B" classification (probable identification) is appropriate and conservative given the single-witness nature of the report. While this case holds limited significance for UAP research, it demonstrates the value of trained aviation personnel as observers and illustrates how natural phenomena can produce striking aerial displays. The case also highlights the importance of temporal context: without knowledge of the Geminid shower timing, this might have appeared more anomalous. For aviation safety purposes, this represents a routine (if spectacular) observation of space debris entering the atmosphere, posing no threat to aircraft.
