On May 23, 2010, at approximately 22:45 (10:45 PM), multiple witnesses in Auberville-la-Renault, a commune in the Seine-Maritime department of Haute-Normandie, observed the evolutions of an orange luminous object in the night sky. The object exhibited unusual flight characteristics, initially moving horizontally across the sky before entering a stationary hover. After this hovering phase, the object resumed movement, this time ascending vertically before disappearing beyond the horizon. The entire observation lasted approximately five minutes, during which no sound was detected by any of the witnesses despite the object's proximity and visibility.
The case was officially investigated by GEIPAN (Groupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non Identifiés), France's official UAP investigation unit operated by CNES (Centre National d'Études Spatiales). The investigation was assigned case number 2010-05-02615 and received a 'B' classification, indicating a probable identification with good consistency. Notably, no additional witness reports were collected from the surrounding area despite the multi-witness nature of the initial sighting, suggesting the phenomenon was localized to a specific viewing angle or the witnesses were part of a single group.
GEIPAN investigators concluded that the witnesses had "probably" observed the passage of a Thai lantern (lanterne thaïlandaise), also known as a sky lantern or Chinese lantern. This assessment was based on the object's characteristic orange color, silent operation, relatively slow movement patterns, and the flight profile consistent with a buoyant object subject to wind currents and thermal lift before its fuel source exhausted.

Multiple unidentified witnesses observing together in Auberville-la-Renault. Exact number and backgrounds not specified in available documentation.
"Plusieurs personnes observent dans le ciel les évolutions d'un objet lumineux orangé. Celui-ci se déplace horizontalement puis stationne avant de repartir verticalement et de disparaître à l'horizon. Aucun bruit ne sera entendu durant l'observation."
04 Analyst Notes -- AI Processed
The GEIPAN 'B' classification indicates this case reached a probable identification with reasonable certainty, though not absolute confirmation (which would merit an 'A' classification). The investigator's assessment of a Thai lantern is highly credible given the specific characteristics observed: the distinctive orange glow typical of flame-illuminated paper lanterns, the complete absence of sound (ruling out conventional aircraft or drones), and the flight pattern of horizontal drift followed by vertical ascent as hot air provides lift. The hovering behavior is particularly consistent with a lantern caught in calm air or transitional wind conditions before thermal currents carry it upward.
However, several factors prevent absolute certainty. No physical evidence was recovered, and the lack of corroborating reports from surrounding areas is notable—though this could simply indicate the witnesses were isolated or that others didn't report what they saw. The multiple-witness nature of the sighting adds credibility to the observation details, but the exact number of witnesses remains unspecified in the documentation. The five-minute duration is consistent with typical sky lantern visibility timeframes. The date (May 23, 2010) doesn't correspond to major French celebrations where lantern releases are common, though private celebrations or individual releases occur year-round. The case represents a textbook example of how modern celebratory items have become the most common misidentified objects in UAP reports, replacing the weather balloons and Venus sightings of earlier decades.
05 Theory Comparison
BELIEVER ANALYSIS
Genuine Anomalous Aerial Phenomenon
A minority interpretation might suggest the object represents a genuine unknown aerial phenomenon, citing the precise control demonstrated by the horizontal-to-stationary-to-vertical flight pattern and the lack of visible propulsion or sound signature. However, this interpretation fails to address why the observed characteristics so precisely match known sky lantern behavior and why no other witnesses in surrounding areas reported the phenomenon. The 'B' classification reflects that while absolute certainty is impossible without physical evidence, the preponderance of evidence strongly favors the conventional explanation.
SKEPTIC ANALYSIS
Conventional Aircraft or Drone
Alternative conventional explanations could include distant aircraft with landing lights, helicopters, or aerial drones. However, this theory is contradicted by the complete absence of sound reported by multiple witnesses and the unusual flight pattern of stationary hovering followed by vertical ascent, which is not characteristic of standard aircraft operations. The orange coloration also doesn't match typical aircraft lighting. This explanation is considered unlikely by investigators.
06 Verdict
ANALYST VERDICT
This case is assessed as explained with high confidence. The observed object's characteristics—orange luminosity, silent operation, slow horizontal drift, stationary hovering, vertical ascent, and eventual disappearance—form a nearly perfect match for a Thai/Chinese sky lantern. GEIPAN's 'B' classification appropriately reflects probable identification rather than certain proof, as no physical evidence was recovered and alternative explanations (though unlikely) cannot be completely excluded. The case holds minimal significance for serious UAP research but serves as an important calibration example for identifying one of the most common sources of modern UFO reports. The investigation demonstrates the value of official UAP monitoring programs in quickly identifying and classifying routine phenomena, preventing the accumulation of explained cases in the 'unknown' category. For researchers, this case reinforces the necessity of considering contemporary cultural practices—including the increasing popularity of sky lanterns since the mid-2000s—when evaluating orange, silent, slow-moving nocturnal lights.
