On June 3, 2010, at approximately 00:45 hours, a single witness in Mordelles, Ille-et-Vilaine, observed a stationary ball of light in the night sky. The luminous object remained fixed in position before gradually losing intensity and disappearing from view over a 15-20 second observation period. The witness noted no accompanying sound during the entire observation.
The case was initially published by GEIPAN with a 'C' classification (unidentified after investigation). However, following publication, an internet user contacted GEIPAN suggesting the possibility of an Iridium flare as the explanation. GEIPAN investigators subsequently verified this hypothesis through astronomical data and satellite tracking records.
GEIPAN's analysis confirmed that the witness's description precisely matched the characteristics of an Iridium satellite flare—a rare and spectacular phenomenon caused by sunlight reflecting off the polished antenna surfaces of Iridium communication satellites. The timing, location, and visibility parameters all aligned perfectly with a confirmed Iridium flare event occurring at that exact moment and location. The case was reclassified to 'A' (identified with certainty) as an Iridium flash, though investigators noted the witness failed to provide information about the phenomenon's elevation angle in the sky.

03 Key Witnesses
Anonymous Witness 1
Civilian observer
medium
Single witness who observed and reported the phenomenon to GEIPAN. Provided accurate description of visual characteristics but lacked technical knowledge to identify the satellite flare.
"Une boule de lumière fixe qui perd de sa luminosité. Aucun bruit remarqué durant l'observation."
04 Analyst Notes -- AI Processed
This case represents a textbook example of proper scientific investigation methodology and the value of public collaboration in UAP research. The initial 'C' classification demonstrates appropriate caution when witness descriptions don't immediately match known phenomena. The subsequent reclassification shows GEIPAN's commitment to accuracy over maintaining mystery. The citizen scientist who identified the Iridium flare possibility played a crucial role in case resolution.
Iridium flares are indeed rare and spectacular events that can easily be mistaken for anomalous phenomena by observers unfamiliar with satellite behavior. These flares can reach magnitude -8 or brighter—far more brilliant than Venus—and their sudden appearance and gradual fade matches the witness description perfectly. The 15-20 second duration is consistent with typical Iridium flare events. The lack of sound corroborates the satellite explanation, as objects at orbital altitude (approximately 780 km for Iridium satellites) produce no audible noise. The one deficiency in the witness report—failure to note elevation angle—is typical of untrained observers and doesn't diminish the credibility of the explanation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Missing Elevation Data Limitation
While the Iridium flare explanation is compelling and almost certainly correct, GEIPAN noted the witness failed to provide information about the phenomenon's elevation angle in the sky. This represents a gap in the observational data that, while not undermining the satellite explanation, prevents absolute verification of all parameters. A complete report would have included angular position data allowing precise correlation with predicted flare visibility cones. However, given the perfect temporal and location match, this omission is minor.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as an Iridium satellite flare with extremely high confidence. GEIPAN's classification 'A' (identified with certainty) is fully justified by the convergence of multiple factors: precise temporal correlation with predicted Iridium flare events, location match, visual characteristics consistent with flare behavior, and the 15-20 second duration typical of these phenomena. The case holds minimal significance for UAP research but serves valuable educational purposes, demonstrating both how easily spectacular natural/man-made phenomena can be misidentified and the importance of astronomical verification in investigation protocols. It also showcases the effectiveness of crowd-sourced expertise in case resolution.
