On April 25, 1993, multiple witnesses in Gavray, a small town in the Manche department of Normandy, reported observing white lights rotating in the sky at regular intervals. The witnesses described these luminous phenomena appearing periodically, creating a pattern of rotating white beams against the night sky. The sightings generated enough concern to warrant an official GEIPAN investigation.
GEIPAN investigators conducted a thorough field investigation to determine the source of the mysterious lights. Through systematic analysis of witness reports, timing patterns, and on-site examination, investigators were able to trace the light source to its origin. The investigation methodology included interviewing witnesses about the exact location and timing of the observations, as well as conducting a physical survey of the area.
The investigation conclusively determined that the observed lights were not of anomalous origin. GEIPAN's field work unambiguously identified the source as an advertising searchlight installed on the roof of a nearby discotheque. The rotating promotional light, designed to attract customers to the nightclub, was creating the beams of white light that witnesses had interpreted as unexplained aerial phenomena. This case received GEIPAN's "A" classification, indicating a phenomenon that was positively identified with certainty.

04 Analyst Notes -- AI Processed
This case represents a textbook example of successful investigative methodology resulting in positive identification. The GEIPAN classification of "A" (identified with certainty) reflects the unambiguous nature of the findings. The investigators demonstrated thoroughness by not simply dismissing the reports but conducting actual field investigation to verify the source. The regular intervals reported by witnesses perfectly correlate with the behavior of a rotating advertising searchlight, which typically sweeps the sky in predictable patterns.
The case highlights how mundane terrestrial light sources can generate UFO reports when witnesses are unfamiliar with their origin. Advertising searchlights, particularly those mounted on entertainment venues, are a known source of UFO misidentifications, especially in smaller towns where such installations may be novel. The credibility of the witnesses is not in question—they accurately described what they saw. The error lay in the interpretation of an unfamiliar stimulus. This case serves educational value in demonstrating how proper investigation can resolve seemingly mysterious phenomena.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Predictable Misidentification Pattern
This case fits a well-documented pattern of UFO reports generated by unfamiliar terrestrial light sources. Advertising searchlights, particularly in smaller communities where they may be uncommon, frequently generate reports of mysterious lights in the sky. The witnesses' observations were accurate, but their interpretation was influenced by lack of familiarity with the light source.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a misidentification of an advertising searchlight from a local discotheque. The GEIPAN investigation left no ambiguity, and the "A" classification is entirely warranted. The regular intervals, white color, and rotating pattern all perfectly match the characteristics of promotional searchlights commonly used by nightclubs. While the witnesses' reports were genuine, the phenomenon had a prosaic terrestrial explanation. This case has minimal significance for UAP research beyond serving as an example of successful investigation methodology and the importance of field verification. It demonstrates that not all lights in the sky warrant extraordinary explanations, and that systematic investigation can resolve apparent mysteries.
