On the evening of May 6, 2010, a single witness in La Couronne, Charente department, France, observed an unusual aerial phenomenon in the starry night sky. The witness initially perceived a luminous point accompanied by a red point to its right, beneath which was a green point. These colored lights moved together in formation, initially resembling an aircraft with standard navigation lights (red and green position markers). However, the observation took an unexpected turn when the luminous points suddenly separated and departed in opposite directions from each other.
The case was investigated by GEIPAN (Groupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non Identifiés), France's official UFO investigation service operated by CNES (Centre National d'Études Spatiales). The official investigation concluded that while the initial phase of the observation—a luminous point above the horizon with red and green points exhibiting scintillation—was entirely consistent with the perception of a star or planet affected by atmospheric conditions, the second phase presented anomalies. GEIPAN's analysis stated that the separation behavior "ne correspond à aucun phénomène connu" (does not correspond to any known phenomenon), except possibly an optical illusion following the object's disappearance.
GEIPAN classified this case as "C" (insufficient data), noting low strangeness for the observation's beginning but medium strangeness for the conclusion. The investigation determined the case lacked reliable information and corroborating evidence due to being a single-witness event with testimonial inconsistencies and imprecision. The case remains officially unresolved due to insufficient data to reach a definitive conclusion.
02 Timeline of Events
Evening, May 6, 2010
Initial Observation Begins
Witness observes a luminous point in the starry sky accompanied by a red point to its right, with a green point beneath the red one. The configuration resembles aircraft navigation lights.
Shortly after initial sighting
Formation Movement Observed
The three luminous points move together as a unit, reinforcing the witness's impression of observing an aircraft with standard position lights.
Final phase of observation
Unexplained Separation Event
The luminous points suddenly separate from each other and depart in opposite directions—behavior that GEIPAN notes does not correspond to any known phenomenon except possible optical illusion.
May-June 2010
GEIPAN Investigation Initiated
Official investigation conducted by France's CNES-GEIPAN. Case assigned reference number 2010-05-02564.
Investigation conclusion
Classification C Assigned
GEIPAN classifies case as 'C' (insufficient information) due to single witness, testimonial inconsistencies, lack of corroborating evidence, and inability to reach definitive conclusion.

Civilian

Single witness from La Couronne, Charente. GEIPAN investigation noted inconsistencies and imprecision in testimony.
"Ces points lumineux bougent ensemble et font penser à un avion jusqu'à ce qu'ils se séparent et partent dans des directions opposées. (These luminous points moved together and resembled an aircraft until they separated and departed in opposite directions.)"
04 Analyst Notes -- AI Processed
This case presents a classic challenge in UFO investigation: the transition from a conventional explanation to unexplained behavior. GEIPAN's assessment is methodologically sound—the initial observation perfectly matches celestial body misidentification with atmospheric scintillation creating the illusion of colored lights. Stars and planets near the horizon frequently display red and green coloration due to atmospheric refraction, particularly when scintillating.
However, the reported separation and divergent flight paths introduce genuine strangeness that GEIPAN acknowledges cannot be explained by known phenomena. The investigators themselves note this doesn't match conventional explanations beyond optical illusion. The single-witness limitation is critical here—without corroboration, we cannot rule out perceptual effects, eye fatigue, or misinterpretation of separate unrelated phenomena (perhaps a satellite passing near a scintillating star). The witness's own description suggests possible confusion, as they initially thought it resembled an aircraft before the objects separated. The testimonial inconsistencies and imprecision mentioned by GEIPAN further reduce credibility. The lack of details about duration, exact timing, angular measurements, or direction of movement prevents meaningful analysis against astronomical data or flight records.
05 Theory Comparison
BELIEVER ANALYSIS
Genuine Anomalous Aerial Phenomenon
The case presents a genuine unexplained event that GEIPAN itself acknowledges 'ne correspond à aucun phénomène connu' (does not correspond to any known phenomenon). The witness described coherent movement as a single formation followed by controlled separation in opposite directions—behavior inconsistent with natural phenomena or conventional aircraft. While the single-witness limitation is acknowledged, the witness's initial rational explanation attempt (thinking it was an aircraft) followed by observation of impossible behavior suggests a credible anomaly. The official 'C' classification indicates the case cannot be explained, not that it has been debunked.
SKEPTIC ANALYSIS
Optical Illusion and Misperception
The most probable explanation combines celestial misidentification with perceptual error. The initial observation was likely a bright planet (Venus or Jupiter) with atmospheric effects creating colored scintillation. The 'separation' was an optical illusion when the object was obscured by atmospheric conditions or clouds, possibly coinciding with an unrelated aircraft or satellite passing nearby. The witness's expectation of seeing an aircraft may have created confirmation bias, and the single-witness nature with noted testimonial inconsistencies suggests perceptual unreliability.
Multiple Conventional Aircraft Misidentified
Alternative conventional explanation: the witness observed two separate aircraft at different altitudes whose flight paths happened to diverge at the moment of observation. Initial formation-like appearance was coincidental positioning, and the red/green lights were standard aviation navigation lights. The witness misperceived these as a single object that split apart. The lack of sound reporting (common in aircraft misidentification) and imprecise testimony support this possibility.
06 Verdict
ANALYST VERDICT
This case most likely represents a misidentification of celestial objects combined with an optical illusion or perceptual error. The initial observation strongly suggests a bright planet or star (possibly Venus or Jupiter, both visible in May 2010) with atmospheric scintillation creating colored flickering effects. The reported separation is the critical unexplained element, but given the single witness, lack of precise details, and GEIPAN's notation of testimonial inconsistencies, the most probable explanation is that the witness experienced an optical illusion when the celestial object was obscured (by clouds or atmospheric conditions) and misinterpreted this as separation. Alternative mundane explanations include two separate aircraft at different altitudes whose paths diverged, misperceived as a single splitting object. The case is not significant for UFO research due to insufficient data quality, lack of corroboration, and the high probability of conventional explanation. GEIPAN's "C" classification is appropriate—the case cannot be resolved with confidence but lacks the evidence quality to warrant further investigation.
