On January 1, 2013, between 16:00 and 16:30 hours, a witness in Paris observed the silent passage of two successive groups of luminous spheres traveling from west to east across the sky. The witness reported that the first group of lights passed overhead, followed by a second group following the identical trajectory. The objects moved without producing any sound and eventually disappeared over the eastern horizon. The observation occurred during daylight hours in the late afternoon on New Year's Day, a time when celebratory activities were widespread across the city.
The GEIPAN investigation cross-referenced the witness description with meteorological data from the observation time, noting that weather conditions included light westerly winds. The investigative team analyzed the characteristics of the sighting: multiple luminous points organized in two distinct groups, silent flight, west-to-east trajectory consistent with wind direction, and the timing coinciding with New Year's Day celebrations. All evidence pointed toward a conventional explanation.
GEIPAN classified this case as "B" (probable identification with high confidence), concluding that the observed phenomena were almost certainly Thai sky lanterns (lanternes thaïlandaises) released as part of New Year's celebrations. The classification indicates that while no physical evidence was recovered, the convergence of circumstantial evidence—festive date, witness description, wind conditions, and flight characteristics—provides a highly probable conventional explanation.
02 Timeline of Events
16:00
First Group Observed
Witness observes the first group of luminous spheres appearing from the west, traveling silently toward the east over Paris.
16:00-16:30
Second Group Follows Identical Path
A second distinct group of lights appears, following precisely the same west-to-east trajectory as the first group, maintaining silent flight.
16:30
Objects Disappear Over Eastern Horizon
Both groups of luminous objects vanish from sight over the eastern horizon, consistent with distance and potentially descending as fuel depletes.
Post-observation
GEIPAN Investigation Initiated
Witness files report with GEIPAN, France's official UAP investigation service under CNES (Centre National d'Études Spatiales).
Post-investigation
Meteorological Analysis Conducted
GEIPAN investigators review weather data confirming light westerly winds consistent with the observed west-to-east flight path.
Final
Case Classified as Class B
GEIPAN officially classifies the case as Class B: probable identification as Thai sky lanterns based on convergent evidence.

04 Analyst Notes -- AI Processed
This case demonstrates textbook characteristics of sky lantern misidentification. The temporal context is particularly significant: New Year's Day is one of the most common occasions for celebratory sky lantern releases across Europe. The witness description of "multiple luminous points in two groups" is entirely consistent with sky lanterns released in batches, which is standard practice. The silent flight pattern is diagnostic—sky lanterns produce no engine noise, unlike aircraft or drones.
The meteorological correlation strengthens the conventional explanation considerably. GEIPAN's notation of "light westerly winds" (léger vent d'Ouest) perfectly explains the observed west-to-east trajectory. Sky lanterns are passive aerial devices that drift entirely with prevailing winds. The fact that both groups followed "exactly the same trajectory" (toujours la même trajectoire) confirms consistent wind direction at altitude during the observation period. The witness's credibility is not questioned, but rather their unfamiliarity with sky lanterns as an explanation. The late afternoon timing (16:00-16:30) would provide sufficient ambient light to make the flame-powered lanterns visible as luminous objects against the darkening sky.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Misidentified Aircraft or Drones
An alternative conventional explanation could involve misidentified aircraft lights or recreational drones flying in formation. However, this theory is weaker than the sky lantern hypothesis because: (1) the witness specifically noted complete silence, while aircraft and drones produce audible noise, (2) the grouping pattern and trajectory are inconsistent with typical aircraft approach paths to Paris airports, and (3) multiple recreational drones flying in precise formation was less common in 2013 than today. The sky lantern explanation better accounts for all reported characteristics.
06 Verdict
ANALYST VERDICT
GEIPAN's classification of this case as explained (Class B - probable Thai sky lanterns) is well-supported by multiple converging lines of evidence. The probability that this sighting represents anything anomalous is extremely low. The combination of celebratory context, meteorological alignment, characteristic silent flight, formation behavior, and visual description creates an overwhelming case for conventional sky lanterns. This case holds minimal significance for UAP research and serves primarily as an educational example of how atmospheric conditions, timing, and cultural context must be considered when evaluating luminous aerial phenomena. The witness likely observed a genuine phenomenon but lacked the frame of reference to identify commercial sky lanterns, which have become increasingly popular at celebrations across France since the late 2000s.
