On June 14, 2011, multiple witnesses in Fourg, a commune in the Doubs department of eastern France, observed successive passages of a luminous point following a regular trajectory across the night sky. The witnesses reported seeing a bright light moving from southwest to east when looking southward. The phenomenon appeared on multiple occasions following the same path, prompting the witnesses to report it to GEIPAN.
The investigation by GEIPAN quickly determined the identity of the observed object through astronomical data correlation. At the time of the sightings, the International Space Station (ISS) had the cargo vessel ATV2 (Automated Transfer Vehicle 2, named "Johannes Kepler") docked to it, which would have increased its overall brightness. The ISS was making visible passes over the Fourg region with a magnitude of -3.0, making it one of the brightest objects in the night sky and easily observable with the naked eye.
GEIPAN cross-referenced the witness-provided observation times with data from Heavens Above, a satellite tracking website. While there were slight discrepancies in the exact timing, this was attributed to weekly orbital corrections that the ISS undergoes to maintain its proper altitude and trajectory. The observed trajectory from southwest to east while facing south perfectly matched the ISS's ground track over eastern France during this period. This case represents a textbook example of satellite misidentification and demonstrates how even bright, familiar objects in orbit can be perceived as anomalous when observers are unfamiliar with their appearance and behavior.

04 Analyst Notes -- AI Processed
This case exemplifies the importance of astronomical verification in UFO investigations and represents GEIPAN's 'Class A' category—a positive identification with certainty. The witnesses' credibility is actually reinforced by their accurate observation of a repeated trajectory, which demonstrates careful attention to detail rather than misperception. The fact that multiple witnesses independently noted the same phenomenon adds weight to the accuracy of their observational data, even though they misidentified the object.
The presence of ATV2 docked to the ISS is a significant detail that explains the exceptional brightness (magnitude -3.0) of the observation. The ISS alone is typically magnitude -2 to -4 depending on viewing angle and solar illumination, but with an additional large module attached, it would have been particularly prominent. The timing in mid-June 2011 is consistent with the ATV2 mission profile—it launched on February 16, 2011, and remained docked until June 20, 2011, just six days after this sighting. The witnesses were therefore observing the ISS at near-maximum size during this mission. The southwest-to-east trajectory is entirely consistent with the ISS's typical ground track over mid-latitude European locations.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Satellite Misidentification Due to Unfamiliarity
This represents a classic case of observers unfamiliar with satellite appearances reporting a well-known artificial object as anomalous. The ISS is the third-brightest object visible in the night sky after the Sun and Moon when conditions are favorable. The repeating trajectory that prompted the witnesses to report the sighting is actually the key evidence confirming it as an orbiting object rather than an anomaly.
06 Verdict
ANALYST VERDICT
This case is definitively explained as observation of the International Space Station with the ATV2 cargo vessel attached. The confidence level in this explanation is extremely high—approaching 100%—based on perfect trajectory matching, brightness correlation, timing verification through Heavens Above data, and the repeating nature of the sightings matching orbital mechanics. GEIPAN's 'Class A' designation is entirely appropriate. This case has minimal significance as an anomalous phenomenon but serves valuable educational purposes, demonstrating how artificial satellites can be misidentified by even careful observers, and showcasing the methodical approach GEIPAN employs in resolving reported sightings through astronomical data correlation.
