On the evening of February 4, 1988, between 19:45 and 20:30 local time, two witnesses in Calais, a coastal city in northern France, observed an unusual aerial phenomenon. The object was described as a luminous green sphere or ball that moved slowly across the sky from east to west. The sighting occurred during the evening hours when darkness would have made the green luminosity particularly striking against the night sky. The case was officially documented 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 witnesses reported the object's distinctive green coloration and its deliberate, unhurried trajectory across the observable sky. The duration of the sighting, potentially lasting up to 45 minutes, suggests either prolonged observation of a single object or multiple sightings during the timeframe. GEIPAN classified this case as 'C', indicating insufficient data for conclusive analysis. The investigation notes explicitly state that "no other information could be collected," highlighting the fundamental limitation of this case. The lack of additional witness testimony, photographic evidence, radar data, or corroborating reports from the Calais area significantly hampers any comprehensive analysis of the phenomenon.
02 Timeline of Events
19:45
Initial Sighting
Two witnesses in Calais first observe a luminous green sphere in the evening sky, beginning its east-to-west trajectory.
19:45-20:30
Prolonged Observation
The green orb continues its slow movement across the sky from east to west. Witnesses track the object for potentially up to 45 minutes.
20:30
End of Observation
Sighting concludes. Object either moves out of view or disappears. No information on termination circumstances.

04 Analyst Notes -- AI Processed
This case presents classic challenges in UFO investigation: limited witness data, no physical evidence, and no follow-up information. The 'C' classification by GEIPAN reflects this evidential poverty—the case cannot be explained definitively, but equally cannot be thoroughly investigated. The green coloration is noteworthy; green fireballs and meteors are well-documented phenomena, particularly those containing copper compounds. However, the reported slow movement and extended duration (up to 45 minutes) are inconsistent with meteoric activity, which typically lasts seconds. Calais's coastal location near the English Channel raises the possibility of military or maritime activities. The city hosts a major port and is near military installations. Flares, particularly naval or aerial illumination flares, can burn green and descend slowly. The east-to-west trajectory could align with prevailing winds or planned exercises. The time period (late Cold War era, 1988) saw significant military activity in the region. Credibility assessment is impossible without witness backgrounds, but the fact that two independent observers reported the same phenomenon adds minimal corroboration. The lack of widespread reporting from a city of Calais's size (population ~75,000 in 1988) suggests either limited visibility or low strangeness factor.
05 Theory Comparison
BELIEVER ANALYSIS
Unidentified Aerial Phenomenon
The object represents a genuine UAP of unknown origin. The distinctive green luminosity, slow deliberate movement, and extended observation period differentiate it from conventional aircraft or natural phenomena. The fact that two independent witnesses observed the same phenomenon adds credibility. Proponents note that the lack of sound (not mentioned but implied by the absence) and unconventional movement pattern suggest non-conventional technology. The coastal location over a strategic waterway may be significant, as UAP sightings often cluster near military or maritime installations.
SKEPTIC ANALYSIS
Military or Maritime Illumination Flare
The object was most likely a green illumination flare deployed by military or maritime forces operating in or near the English Channel. Green flares are standard naval equipment, often containing barium compounds that produce distinctive green light. Deployed under parachute, such flares descend slowly and can remain visible for extended periods, consistent with the 45-minute observation window. Calais's strategic coastal location near significant shipping lanes and military zones makes this a plausible explanation for the east-to-west trajectory following prevailing winds.
06 Verdict
ANALYST VERDICT
Most likely explanation: military or maritime illumination flare, or possibly a slow-moving fireball/meteor with unusual composition. The green coloration strongly suggests either copper-based pyrotechnics or specific meteoric composition. The slow movement argues against standard meteor activity but is consistent with descending flares under parachute deployment. Confidence level: low-to-moderate. This case lacks the evidentiary foundation for definitive conclusion. Its significance is minimal—it represents a typical low-information sighting that, while officially documented, offers no compelling anomalies that cannot be explained by conventional phenomena. The GEIPAN 'C' classification is appropriate; without additional data, this remains an unresolved but unremarkable case in the UAP database.
