On Christmas Eve 1978, at approximately 21:00 hours, two witnesses in Cournon, Puy-de-Dôme (department 63), observed a luminous object in the night sky. The witnesses reported that the object moved at slow speed while emitting varied colors. The observation continued intermittently, with one witness confirming a second sighting around 23:00 hours, noting that the object had changed position during the interval. The case was officially 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 GEIPAN investigation file notes that the witness depositions were "très succinctes" (very brief), providing limited detail about the nature of the observation. No additional witnesses came forward to corroborate the sighting despite the two-hour timeframe and the Christmas Eve timing when many people would have been outdoors or traveling. The object's slow movement, color variations, and ability to change position over a two-hour period were the primary characteristics documented.
GEIPAN classified this case as "C" in their standardized classification system, which typically indicates a case where the information is insufficient to determine the nature of the phenomenon with certainty. The lack of detailed witness testimony, absence of corroborating witnesses, and minimal investigative documentation limit the analytical value of this case.
02 Timeline of Events
21:00
Initial Observation
Two witnesses observe a luminous object in the sky over Cournon, Puy-de-Dôme. The object is moving at slow speed and emitting varied colors.
21:00-23:00
Observation Period
Object remains visible intermittently. At least one witness continues monitoring the phenomenon over the two-hour period.
23:00
Second Confirmed Sighting
One witness confirms observing the object again, noting it has changed position in the sky since the initial observation.
Post-incident
GEIPAN Investigation
Official investigation conducted by GEIPAN (CNES). Case classified as 'C' due to insufficient information. Investigation notes indicate witness depositions were very brief with limited detail.

04 Analyst Notes -- AI Processed
This case presents significant analytical challenges due to the extremely limited documentation. The brief witness statements provide no information about the object's size, altitude, trajectory details, angular measurements, or distinctive features beyond "varied colors" and "slow movement." The Christmas Eve timing (24 December) is notable, as this date historically sees numerous misidentifications of astronomical objects, aircraft, and atmospheric phenomena due to increased public attention to the night sky and holiday lighting displays.
The GEIPAN "C" classification appropriately reflects the ambiguous nature of this case. Several conventional explanations warrant consideration: Venus or another bright planet would have been visible in the evening sky and could appear to "move" due to atmospheric refraction and the witnesses' own motion. The two-hour observation period with position changes could indicate the natural progression of celestial objects across the sky, which untrained observers often perceive as anomalous movement. The "varied colors" description is consistent with atmospheric scintillation effects on bright stars or planets viewed near the horizon. Aircraft with navigation lights, particularly during the busy holiday travel period, could also account for colored lights appearing to move slowly at distance. The absence of corroborating witnesses despite the duration and timing of the event suggests the phenomenon may not have been particularly remarkable to other observers.
05 Theory Comparison
BELIEVER ANALYSIS
Unidentified Aerial Phenomenon
The slow-moving, color-changing luminous object observed over a two-hour period represents a genuinely anomalous phenomenon that warrants classification as an unidentified aerial phenomenon. The witnesses' decision to observe and report the object suggests it exhibited characteristics sufficiently unusual to draw sustained attention. The ability of the object to change position and reappear over an extended timeframe could indicate controlled movement inconsistent with conventional explanations. The GEIPAN 'C' classification leaves open the possibility of a genuinely unknown phenomenon.
SKEPTIC ANALYSIS
Astronomical Object Misidentification
The most parsimonious explanation is misidentification of a bright celestial object (Venus, Jupiter, or bright star like Sirius) viewed under conditions causing atmospheric scintillation. The 'slow movement' and position change over two hours is consistent with the natural progression of celestial objects across the sky, which can appear anomalous to untrained observers. The varied colors are characteristic of atmospheric refraction effects, particularly when viewing bright objects near the horizon during winter months. The Christmas Eve timing may have drawn unusual attention to objects that would normally go unnoticed.
Conventional Aircraft
Aircraft navigation lights viewed at distance during the busy Christmas Eve travel period could account for the observation. Modern aircraft lighting systems include multiple colors (red, green, white) that could be perceived as 'varied colors.' The slow apparent speed could result from an aircraft traveling toward or away from observers, minimizing angular velocity. The position changes over two hours could represent multiple aircraft on similar flight paths being perceived as a single recurring phenomenon.
06 Verdict
ANALYST VERDICT
Most likely explanation: astronomical misidentification (Venus, bright star, or planet) with possible contribution from atmospheric effects. Confidence level: Medium-Low. The case lacks sufficient detail for definitive analysis, but the characteristics described—slow movement, color variations, visible over extended period—align closely with common astronomical misidentifications, particularly during winter months when atmospheric conditions can cause pronounced scintillation. The GEIPAN "C" classification appropriately indicates insufficient data. This case holds minimal significance for UAP research due to the brevity of witness testimony and absence of corroborating evidence. It serves primarily as an archival example of reports that cannot be adequately investigated due to limited initial documentation.
