On August 22, 1979, at approximately 22:45 (10:45 PM), two witnesses near a golf course in Belvédère-Campomoro, Corsica observed an intriguing luminous point in the night sky. The object initially appeared stationary at an estimated altitude of 100-150 meters directly above the golf course. After remaining fixed for a period, the light began moving westward while simultaneously decreasing in brightness. One witness retrieved binoculars to observe the phenomenon more closely and reported seeing "two yellow parallelograms" through the optical device. The geometric shapes visible through magnification caught the witnesses' attention, though no other individuals came forward to corroborate the sighting despite the coastal location where other observers might have been present. GEIPAN investigators classified this case as "B" (likely explained with good consistency), concluding the phenomenon was most probably an aircraft illuminated by sunlight. The investigation noted that the geometric parallelogram shapes observed through binoculars were consistent with optical aberrations commonly produced by low-quality binoculars when viewing point light sources, a well-documented phenomenon in optical physics.

04 Analyst Notes -- AI Processed
This case presents a textbook example of witness perception being influenced by optical equipment limitations. The critical detail is the timing discrepancy: the sighting occurred at 22:45 (10:45 PM) in late August, yet GEIPAN's conclusion references sunlight illumination of an aircraft. In Corsica at this latitude in late August, civil twilight ends around 21:00-21:15, making direct solar illumination of an aircraft at 22:45 astronomically impossible—the sun would be approximately 15-20 degrees below the horizon. The binocular observation is particularly telling. The witness's description of "two yellow parallelograms" is consistent with internal reflections, chromatic aberration, or astigmatic distortion in budget optical equipment when viewing bright point sources against a dark background. Aircraft anti-collision lights (strobing red/white) and navigation lights (green/red wingtips, white tail) could appear as geometrically distorted shapes through poor-quality optics. The westward movement and decreasing intensity align with an aircraft on a departure trajectory from one of Corsica's airports, climbing and banking away from the observation point. The lack of corroborating witnesses in a tourist area during peak summer season suggests the phenomenon was likely mundane enough that others either didn't notice or didn't find it remarkable.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Aircraft Navigation Lights with Optical Aberration
A conventional aircraft (likely departing from Ajaccio or Figari airports) was observed through low-quality binoculars that introduced chromatic aberration, astigmatism, or internal reflections. The stationary phase represents the aircraft approaching the observer's position before banking westward on its departure route. The 'parallelogram' shapes are classic optical distortions when viewing bright point sources through budget optics. The decreasing intensity indicates increasing distance as the aircraft climbed and departed.
06 Verdict
ANALYST VERDICT
This case is almost certainly an aircraft misidentification, though GEIPAN's stated explanation contains a significant error regarding solar illumination timing. The most plausible scenario involves an aircraft departing from Ajaccio-Napoléon Bonaparte Airport (approximately 50km north) or Figari-Sud Corse Airport (approximately 40km southeast), with its navigation and position lights creating a bright point source. When viewed through low-quality binoculars, these lights produced optical aberrations that appeared as geometric shapes. The 22:45 timing rules out sunlight reflection; the aircraft was likely visible due to its own lighting systems. The witnesses' puzzlement is understandable—aircraft lights through distorting optics can create unfamiliar visual effects—but the behavior (stationary hovering followed by westward movement and altitude gain) precisely matches standard departure patterns. The case's low significance stems from the single observation, lack of extraordinary characteristics, and straightforward conventional explanation, despite the investigative report's timing inconsistency.
