On December 19, 2009, between 20:30 and 21:30 local time, multiple witnesses observed intense red lights moving erratically over the ocean off the coast of Saint-Leu, La Réunion. The principal witness reported five distinct observation sequences during which the same red light appeared to perform random movements above the water. The sighting lasted approximately one hour, with the luminous phenomenon repeatedly appearing and disappearing.
The primary witness did not file an official report with local gendarmerie, and no additional witness testimonies were collected by authorities during the initial investigation period. The case remained unresolved through the standard GEIPAN investigative process due to lack of physical evidence and limited witness cooperation.
On June 9, 2010—nearly six months after the incident—the principal witness contacted GEIPAN by letter to clarify the nature of the observation. The witness confirmed that the observed phenomenon was a Thai lantern (lanterne thaïlandaise), also known as a sky lantern or Chinese lantern. This self-identification by the witness led to GEIPAN classifying the case as 'A' (fully explained with certainty), representing a conventional phenomenon that was initially misidentified.

03 Key Witnesses
Anonymous Principal Witness
civilian
high
Primary observer who witnessed the phenomenon over five separate sequences. Demonstrated intellectual honesty by voluntarily contacting GEIPAN six months later to provide correct identification.
"Par courrier du 09 juin 2010, le témoin principal informe le GEIPAN que son observation était une observation d'une lanterne thaïlandaise."
04 Analyst Notes -- AI Processed
This case represents a textbook example of witness self-correction and the importance of follow-up investigation. The six-month delay between observation and identification is notable—it suggests the witness may have conducted independent research or encountered similar phenomena that allowed them to recognize the true nature of what they observed. The initial description of 'intense red lights' with 'random movements' over the ocean is entirely consistent with the behavior of sky lanterns, which drift on wind currents and can appear to move erratically from a distance.
The lack of formal gendarmerie reporting and absence of corroborating witnesses weakens the evidentiary value of this case, though the witness's voluntary clarification demonstrates good faith. Thai lanterns are paper lanterns with a small heat source that causes them to rise and drift, typically displaying a characteristic red-orange glow. They have been responsible for numerous UFO reports globally, particularly in coastal areas where their movement over dark water can create dramatic visual effects. The classification as 'A' by GEIPAN is appropriate and demonstrates the agency's evidence-based approach to case resolution.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Insufficient Initial Investigation
The case demonstrates the challenges of UFO investigation when witnesses don't immediately report to authorities. Without gendarmerie involvement, physical evidence collection, or corroborating witness interviews, the case relied entirely on one witness's retrospective self-assessment. While the sky lantern explanation is highly plausible and likely correct, the six-month delay and lack of contemporaneous investigation means we cannot definitively rule out other conventional explanations such as boat flares, drones, or other aerial phenomena.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a misidentification of one or more Thai sky lanterns. The witness's own admission, combined with the behavioral characteristics described (red lights, erratic movement pattern, appearance over ocean, approximately one-hour duration with intermittent visibility), perfectly matches the known properties of sky lanterns. The case holds minimal significance for UAP research but serves valuable educational purposes: it demonstrates how conventional objects can be initially misperceived, the importance of witness honesty in self-correction, and the effectiveness of allowing time for witnesses to reconsider their observations. The low priority rating reflects the complete resolution and lack of anomalous characteristics once properly identified.
