On August 23, 1990, at approximately 23:00 hours (11:00 PM), a single witness in Arzenc-de-Randon, a commune in the Lozère department of southern France, observed an unusual aerial phenomenon. The witness reported seeing a very bright luminous flash that pulsed at a regular cadence of approximately three seconds. The object moved very rapidly across the sky and remained visible for 30 to 40 seconds before disappearing from view.
The incident occurred in a rural area of the Languedoc-Roussillon region, characterized by low light pollution and clear night skies typical of the mountainous terrain. No additional witnesses came forward, and no corroborating evidence such as photographs, radar data, or physical traces were documented. The GEIPAN investigation file notes explicitly that no other information is available regarding this observation.
GEIPAN classified this case as "C" (likely explained), suggesting investigators determined a conventional explanation was probable despite limited investigative data. The brief nature of the sighting, single witness account, and lack of detailed testimony or supporting evidence contributed to the straightforward classification and minimal investigation depth.

04 Analyst Notes -- AI Processed
This case presents several characteristics consistent with conventional aerial phenomena rather than genuinely anomalous activity. The regular three-second pulsing pattern is highly indicative of aircraft navigation lights, which flash at standardized intervals for collision avoidance. The "very rapid" movement described by a single ground observer could easily be a misperception of distance and speed, common when observers lack reference points in night sky observations.
The witness credibility cannot be properly assessed due to the sparse documentation. GEIPAN's "C" classification indicates their analysts likely identified this as an aircraft, satellite with tumbling rotation causing regular brightness variations, or possibly a meteor with unusual fragmentation pattern. The 30-40 second duration is too long for a typical meteor but consistent with an aircraft passing overhead. The lack of follow-up investigation or additional witness canvassing suggests GEIPAN investigators found the initial explanation sufficiently convincing to warrant minimal resource allocation. The rural location and late hour (23:00) may explain why only a single witness was available to observe the phenomenon.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Aircraft Navigation Lights
The most probable explanation is a conventional aircraft passing overhead at night. Aircraft are equipped with anti-collision strobe lights that flash at regular intervals (typically 40-100 flashes per minute, or approximately every 1-3 seconds). The 'very bright' luminous flash and the precise three-second cadence strongly match aircraft strobe characteristics. The apparent rapid movement is consistent with an aircraft's angular velocity as seen from the ground, especially if it passed relatively close to the observer's position. The 30-40 second duration matches the time required for an aircraft to traverse the visible sky from horizon to overhead.
06 Verdict
ANALYST VERDICT
This case almost certainly represents a misidentification of a conventional aircraft. The regular three-second pulsing pattern is the signature characteristic of aircraft anti-collision strobes, which are specifically designed to flash at predictable intervals. Combined with the rapid apparent movement, nighttime observation conditions, single witness with no technical background indicated, and GEIPAN's "C" classification, the evidence strongly supports a mundane explanation. The case holds minimal significance for UAP research and serves primarily as an example of how routine aerial traffic can appear anomalous to casual observers under limited observation conditions. Confidence level: High (85-90%).
