On May 28, 2008, at approximately 00:04 hours (local time, GMT+2), a single witness in Bergerac, Dordogne observed a rapid passage of a luminous object traversing the night sky. The witness reported the object following a straight-line trajectory in a northwest direction across the celestial sphere. The observation occurred in the early morning hours in this southwestern French town, located in the Aquitaine region.
GEIPAN (Groupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non Identifiés), France's official UFO investigation organization operated by CNES (Centre National d'Études Spatiales), received and investigated this report. The case was assigned classification 'B' in GEIPAN's system, which indicates a phenomenon that has been probably identified with a high degree of certainty.
Following investigation, GEIPAN analysts determined the witness had most likely observed a passage of the International Space Station (ISS). This conclusion was reached by cross-referencing the reported direction (northwest) and timing (00:04 local time) with documented ISS orbital passes over France on that specific date. The ISS, when illuminated by the sun while passing overhead during twilight or nighttime hours, appears as a bright, fast-moving point of light traveling in a straight line—precisely matching the witness description.

04 Analyst Notes -- AI Processed
This case represents a textbook example of ISS misidentification, one of the most common sources of UFO reports in the modern era. The witness's description—a bright, fast-moving luminous object traveling in a straight line—is entirely consistent with satellite or ISS observations. GEIPAN's methodology demonstrates solid investigative practice: they verified the sighting time and direction against known ISS orbital data for May 28, 2008.
The credibility of the witness cannot be fully assessed due to limited information in the case file, but there are no indicators of fabrication or sensationalism. The witness reported exactly what they saw without embellishment. The single-witness nature of the report and the mundane characteristics of the observation (no unusual maneuvers, color changes, or anomalous behavior) support the prosaic explanation. The ISS typically takes 2-4 minutes to cross the visible sky, appears magnitude -2 to -4 (brighter than most stars), and follows predictable trajectories that can be verified against orbital mechanics databases. The northwest trajectory is consistent with typical ISS passes over southwestern France at that latitude.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Aircraft or High-Altitude Satellite
While GEIPAN concluded ISS, other conventional explanations could include high-altitude aircraft with landing lights visible, or another bright satellite such as an Iridium satellite during a flare event. However, the northwest trajectory and timing make ISS the most probable candidate. Aircraft would typically show navigation lights (red/green) and possibly show less linear motion. The description lacks the characteristic bright flash of an Iridium flare, which lasts only seconds.
06 Verdict
ANALYST VERDICT
This case is definitively explained as an ISS observation. GEIPAN's 'B' classification (probably identified) is appropriate and likely conservative—this could arguably merit an 'A' classification (certainly identified) given the precise correlation between reported characteristics and ISS orbital data. The case holds minimal research value beyond serving as a calibration example for distinguishing spacecraft from anomalous phenomena. It demonstrates the importance of cross-referencing sighting reports with known spacecraft schedules, a fundamental step in any competent UFO investigation. No further investigation is warranted, and this case should be considered closed with high confidence in the ISS explanation.
