On Saturday evening, November 26, 2011, at precisely 21:05 (9:05 PM), a single witness in Saint-Brieuc, Brittany observed four luminous white spheres moving silently across the sky in horizontal formation. The observation lasted approximately five minutes, during which the witness noted the objects maintained a consistent trajectory and complete silence throughout their passage. The witness described the objects as white luminous balls that moved in a group formation, traveling from the southwest direction.
GEIPAN's official investigation determined that the sighting characteristics aligned closely with Chinese lanterns (lanternes thaïlandaises): multiple light points moving as a group, traveling in the direction of prevailing winds (from the southwest), limited duration of visibility, and occurrence on a Saturday evening when festive events are common. The investigation was conducted by France's official UFO investigation agency, part of the French space agency CNES (Centre National d'Études Spatiales).
The case received a "B" classification from GEIPAN, indicating a probable identification with a high degree of confidence. However, investigators noted one minor discrepancy: the witness specifically described white lights, whereas Chinese lanterns—even white-colored ones—typically emit a yellow-orange glow due to the flame source. This small anomaly was insufficient to prevent classification but was deemed worthy of documentation.
02 Timeline of Events
21:05
Initial Observation
Witness first observes four luminous white spheres appearing in the sky over Saint-Brieuc, moving in formation from the southwest direction.
21:05-21:10
Silent Horizontal Movement
The four objects continue moving horizontally across the sky in complete silence, maintaining group formation and consistent trajectory aligned with southwest wind direction.
21:10
End of Observation
After approximately five minutes of observation, the objects disappear from view, likely having exhausted their fuel source or moved beyond visible range.

Official Report Filed
Witness submits testimony to GEIPAN for official investigation and classification.
Post-Investigation
GEIPAN Classification
GEIPAN completes investigation and assigns classification 'B' - probable identification as Chinese/Thai lanterns, noting all characteristics match except for reported white color versus typical yellow-orange.

04 Analyst Notes -- AI Processed
This case represents a textbook example of responsible UFO investigation and classification. GEIPAN's methodology demonstrates proper scientific rigor: they identified multiple corroborating factors (wind direction matching object trajectory, timing consistent with festive events, group behavior typical of lanterns, duration matching lantern burn time) while honestly acknowledging the one discrepancy (color description). The Saturday evening timing at 21:05 is indeed typical for celebrations or events where lanterns might be released.
The witness credibility appears neutral—there's no indication of multiple witnesses to corroborate the sighting, nor any suggestion of unreliability. The single-witness nature and lack of additional documentation (photographs, video, or radar data) appropriately places this in the low-priority category. The silent movement strongly supports the lantern hypothesis, as motorized craft would generate noise. The five-minute duration aligns perfectly with typical Chinese lantern flight times before the fuel source is exhausted.
05 Theory Comparison
BELIEVER ANALYSIS
Anomalous Craft in Formation
A minority interpretation might suggest the objects represent genuinely anomalous phenomena, potentially structured craft flying in formation. Proponents would emphasize the anomalous white color that even GEIPAN acknowledged doesn't match lantern characteristics, the precise formation maintenance, and controlled horizontal movement. However, this interpretation fails to address the strong correlation with wind direction, typical lantern timing, and absence of any extraordinary maneuvers or characteristics beyond what lanterns could exhibit.
SKEPTIC ANALYSIS
Atmospheric Light Phenomenon
Alternative prosaic explanation could involve unusual atmospheric light reflection or refraction effects, possibly from ground-based light sources interacting with low clouds or fog. The white color description might support this theory better than lanterns. However, this explanation struggles to account for the precise group formation, consistent trajectory, and five-minute duration with maintained formation integrity.
06 Verdict
ANALYST VERDICT
This case is almost certainly explained as Chinese/Thai lanterns released during a Saturday evening celebration or festive event. Confidence level: approximately 85-90%. The evidence supporting this conclusion includes: movement direction matching prevailing southwest winds, group formation behavior, silent operation, limited duration, and appropriate timing for festive activities. The single unexplained element—the white color rather than yellow-orange—could be attributed to witness perception, distance effects, or atmospheric conditions affecting color appearance. GEIPAN's "B" classification (probable identification) is appropriate and demonstrates the value of systematic investigation even for cases with mundane explanations. This case holds minimal significance for anomalous phenomena research but serves as a useful reference example for lantern identification.
