On February 13, 1979, at approximately 21:45, a witness and their children observed a large white luminous sphere traveling at low altitude across the sky of Trévoux in the Ain department of France. The object moved in a west-to-east trajectory and was described as round and extremely brilliant, with numerous lights sparkling from within. Three colored lights—yellow, green, and red—were observed flashing beneath the main object. Despite observing the phenomenon for two to three minutes, the witness could not identify what they were seeing.
The GEIPAN investigation revealed a pattern of similar sightings in the area. Multiple witnesses reported seeing a white sphere following the same flight path since December 1978, suggesting recurring activity over a two-month period. Witnesses also reported regular electrical voltage drops in the sector during this timeframe. Additionally, a separate witness reported observing a different object on December 4, 1978, at approximately 18:00—a trapezoidal craft with a rectangular base hovering at low altitude, illuminated by red lights and emitting a sound resembling a helicopter.
Air traffic control confirmed no aircraft were detected on radar at the reported dates and times. While investigators hypothesized that some sightings might involve light aircraft from nearby aerodromes, available information was insufficient to confirm this theory. The case was classified as 'C' by GEIPAN, indicating insufficient data to reach a definitive conclusion about the phenomena observed in the Trévoux region during this period.

04 Analyst Notes -- AI Processed
This case presents several factors worthy of analytical consideration. The multi-witness nature of the primary sighting (parent and children) provides some corroboration, though the lack of independent witness statements limits cross-verification. The recurring nature of sightings over a two-month period (December 1978 to February 1979) following the same west-to-east trajectory suggests either a pattern of misidentification of conventional aircraft or genuine anomalous activity with consistent flight characteristics.
The reported electrical voltage fluctuations in the area during the sighting period are intriguing but require caution—no documentation links these power irregularities directly to the sightings, and correlation does not imply causation. The description of colored lights (yellow, green, red) and the sparkling internal illumination could suggest conventional aircraft navigation lights viewed under atmospheric conditions causing optical effects. However, the December 4 sighting describes distinctly different object characteristics (trapezoidal shape, hovering capability, helicopter-like sound), suggesting either multiple phenomena or misidentification of a helicopter. The radar-negative confirmation from air traffic control is significant, though low-altitude light aircraft flying VFR (Visual Flight Rules) might not appear on surveillance radar. The proximity to aerodromes supports the conventional aircraft hypothesis, yet GEIPAN's inability to confirm this after investigation indicates the evidence remained ambiguous.
05 Theory Comparison
BELIEVER ANALYSIS
Genuine Anomalous Phenomenon
The recurring nature of sightings following identical flight paths, combined with radar-negative confirmation and electrical disturbances, suggests something beyond conventional aircraft. The witnesses' inability to identify the objects despite clear viewing conditions and sufficient observation time (2-3 minutes) indicates these may have been craft with unconventional characteristics. The correlation with electrical voltage drops, if genuine, would support the presence of objects generating electromagnetic effects.
SKEPTIC ANALYSIS
Light Aircraft from Local Aerodromes
The most probable explanation involves light aircraft operating from nearby aerodromes in the region. The colored lights correspond to standard aircraft navigation lighting (red, green, white), and the west-to-east trajectory could represent a common flight path. The sparkling internal lights might be cabin or instrument lighting viewed through atmospheric conditions. Low-altitude VFR flights might not appear on air traffic control radar, explaining the radar-negative result.
Misidentified Helicopter
The December 4 sighting specifically describes characteristics consistent with a helicopter: hovering capability, red lights, and helicopter-like sound. This witness appears to have correctly identified the sound but mischaracterized the shape. The same explanation might apply to some of the other sightings, particularly given the low altitude and hovering/slow movement descriptions.
06 Verdict
ANALYST VERDICT
This case most likely involves misidentification of conventional aircraft operating from nearby aerodromes, though the evidence remains inconclusive. The colored navigation lights, the west-to-east flight path, and the presence of local aerodromes all support this hypothesis. However, several factors prevent definitive conclusion: the radar-negative confirmation, the consistent low-altitude trajectory reported across multiple sightings, and the witness's inability to recognize the object despite a 2-3 minute observation period. The December 4 sighting appears to be a separate incident, possibly involving a helicopter, which the witness correctly identified by sound. This case is significant primarily as an example of how recurring sightings in areas with air traffic can create patterns that resist easy explanation without comprehensive flight data. The GEIPAN 'C' classification appropriately reflects the ambiguous nature of available evidence—suggestive of conventional explanation but lacking confirmation.
