On September 8, 2009, at 21:14 local time, a single witness in Le Taillan-Médoc, Gironde department, observed a bright, non-blinking light moving rapidly across the sky from west to east along a straight trajectory. The witness reported the luminous object traveling at high speed across the southern horizon without any flashing or strobing characteristics typical of conventional aircraft navigation lights. GEIPAN investigators conducted a correlation analysis with astronomical databases and determined that the International Space Station (ISS) was visible from this location during the exact timeframe of the observation. According to Calsky astronomical tracking data, the ISS passed over the southern horizon traveling west to east between 21:07 and 21:14—precisely matching the witness's reported observation time and trajectory. The French space agency CNES, through its GEIPAN division, classified this case as "B" (likely identified with high probability). The investigation concluded that the witness observed a routine ISS overhead pass, with the station's reflected sunlight creating the appearance of a bright, steady light moving across the night sky. GEIPAN noted that while the testimony was sincere, the description was too summary for in-depth analysis, and the correlation with ISS orbital data provided a straightforward conventional explanation.

Single witness from Le Taillan-Médoc who reported the sighting to GEIPAN. No additional background information available in the official file.
"Une lumière vive et sans clignotement qui se déplace à une allure rapide d'Ouest en Est sur une trajectoire rectiligne. (A bright light without blinking that moved at a rapid pace from west to east on a straight trajectory.)"
04 Analyst Notes -- AI Processed
This case represents a textbook example of ISS misidentification, demonstrating how unfamiliarity with satellite visibility can lead to UFO reports. The witness's description—bright light, no blinking, rapid movement, straight trajectory, west-to-east direction—perfectly matches the visual characteristics of an ISS pass. The timing correlation is particularly compelling: the witness reported 21:14, falling within the 21:07-21:14 visibility window confirmed by Calsky orbital tracking. The witness credibility appears neutral; there's no indication of fabrication or exaggeration, simply unfamiliarity with identifying satellites or space stations in the night sky. GEIPAN's assessment that the testimony was "très peu étrange" (very little strange) and "sommaire" (summary/basic) indicates the investigators found nothing anomalous beyond the witness's lack of recognition. The classification as "B" rather than "A" (definitively identified) likely reflects the absence of photographic evidence or multiple witness corroboration, though the circumstantial evidence is overwhelming.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Satellite or High-Altitude Aircraft
Even if not the ISS specifically, the description perfectly matches any bright satellite pass or high-altitude aircraft at twilight. The straight trajectory, constant brightness, lack of blinking, and west-to-east movement are all typical of objects in Earth orbit reflecting sunlight. The witness simply observed a mundane space-age phenomenon unfamiliar to the general public.
06 Verdict
ANALYST VERDICT
This case is almost certainly an observation of the International Space Station, with probability exceeding 95%. The temporal and directional correlation with confirmed ISS orbital data leaves virtually no room for alternative explanations. The witness appears to have been unfamiliar with satellite recognition and reported what they honestly perceived as unusual. This case has minimal significance for anomalous phenomena research but serves as a valuable educational example of how routine space objects can be misidentified. The GEIPAN "B" classification is appropriate and well-justified.
