Between July 15-17, 2010, a witness in Aix-en-Provence, Provence-Alpes-Côte d'Azur region, reported observing a powerful luminous phenomenon in the western sky over three consecutive evenings. The witness photographed a bright point of light that appeared around 22:00 (10:00 PM) and descended toward the horizon before disappearing around 23:10 (11:10 PM) each night. The object remained visible for up to 60 minutes per observation, appearing at the same position in the sky on all three nights.
GEIPAN's official investigation reconstructed the observation direction, confirming a cone-shaped viewing angle centered toward the west. The witness described the phenomenon as an extremely powerful luminous point in the sky that descended gradually toward the horizon. Multiple photographs were taken by the primary witness, though other persons present at the time did not provide testimony to investigators.
The case was thoroughly investigated by GEIPAN (Groupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non identifiés), the official French government UFO investigation agency operated by CNES (Centre National d'Études Spatiales). Astronomical analysis definitively identified the observed object as the planet Venus, which had a magnitude of -4.1 at the time and was positioned in the exact portion of sky described by the witness.

Primary witness who observed and photographed the phenomenon over three consecutive nights in Aix-en-Provence. Provided detailed testimony and photographic evidence to GEIPAN investigators.
"Point lumineux très puissant dans le ciel, observé pendant plusieurs jours consécutifs au même endroit pendant de longues minutes (jusqu'à 60 min), descendant vers l'horizon."
04 Analyst Notes -- AI Processed
This case represents a textbook example of Venus misidentification, one of the most common sources of UFO reports worldwide. The characteristics reported by the witness—a stationary, extremely bright point of light visible at the same location over multiple consecutive nights, gradually descending toward the western horizon—are classic signatures of a bright planet observation. Venus, with its exceptional magnitude of -4.1 during this period, would have been the brightest object in the night sky aside from the Moon.
GEIPAN's investigation methodology was exemplary, employing astronomical reconstruction to verify the planet's position matched the witness's described viewing angle. The consistency of timing (appearing around 22:00, disappearing around 23:10) and direction (westward) across three nights aligns perfectly with Venus's predictable celestial mechanics. The witness's unfamiliarity with astronomical phenomena, combined with Venus's extraordinary brightness during this apparition, explains the perceived anomaly. This case received GEIPAN's 'A' classification, indicating complete identification with zero ambiguity—the highest level of certainty in their classification system.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Observer Unfamiliarity with Night Sky
The witness's perception of anomaly stems from lack of astronomical knowledge rather than observation of anything unusual. The described behavior—appearing at the same time and place over multiple nights, descending toward the western horizon—is exactly what any celestial object does due to Earth's rotation. Venus's exceptional brightness during this apparition made it appear unusual to someone unfamiliar with planetary observations. The fact that other witnesses present did not report the phenomenon suggests they recognized it as a natural celestial object.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a misidentification of the planet Venus. GEIPAN's classification 'A' represents absolute certainty, indicating no ambiguity whatsoever in the identification. The investigation's astronomical analysis, directional reconstruction, and correlation with Venus's known position, magnitude, and movement patterns provide conclusive evidence. The witness's honest reporting and photographic documentation allowed investigators to perform thorough analysis, making this case valuable as an educational example of how bright planets can be misperceived as anomalous phenomena by observers unfamiliar with the night sky. The case holds minimal significance as a UFO phenomenon but serves as important documentation of common misidentification patterns for investigative training purposes.
