On October 8, 2018, at approximately 05:30 local time, a single witness in La Bouëxière, France, observed a white luminous point traversing the pre-dawn sky while smoking a cigarette outside her home. The witness described the object as larger and brighter than a star, appearing in the northwest sky and moving with a linear, descending trajectory at constant velocity before disappearing at the southeastern horizon after approximately five minutes. The witness had the presence of mind to film the phenomenon with her mobile phone and contacted GEIPAN the same day, submitting both a completed questionnaire and video evidence two days later. GEIPAN investigators conducted a thorough analysis of the sighting characteristics: the object's appearance (white, larger than a star, constant luminosity), its linear trajectory disappearing at the horizon, and the five-minute observation duration. The angular velocity estimation derived from the witness testimony aligned with artificial satellite passage. Orbital data from Calsky confirmed the International Space Station was not visible at that time, but multiple geostationary satellites were transiting the witness's sky, with two following trajectories closely matching the described path. The timing of the observation proved significant. At approximately three hours before sunrise and occurring near the autumnal equinox, conditions were optimal for geostationary satellites—normally too dim for naked-eye observation—to become temporarily visible when illuminated by the sun at favorable angles. The submitted mobile phone video, recorded handheld at arm's length, proved too low quality for technical analysis. GEIPAN classified this case as Category A (very probable misidentification with a satellite), citing low strangeness, medium consistency due to the single witness and precise description offset by unusable video evidence.
02 Timeline of Events
05:30
Initial Observation
Witness steps outside her home to smoke a cigarette in the pre-dawn darkness and notices unusual luminous point in the northwestern sky.
05:30-05:35
Object Transit and Recording
Witness observes white luminous point, described as larger and brighter than a star, moving with linear descending trajectory at constant velocity. Witness retrieves mobile phone and films the phenomenon.
05:35
Object Disappears
After approximately five minutes of observation, the luminous point disappears at the southeastern horizon, completing its transit across the visible sky.
08:00 (Day of)
Initial Report to GEIPAN
Witness contacts GEIPAN the same day as the observation to report the sighting.
October 10, 2018
Submission of Evidence
Two days after the sighting, witness submits completed questionnaire and video recording to GEIPAN for official investigation.
Post-Investigation
Calsky Analysis and Classification
GEIPAN investigators use Calsky orbital data to rule out ISS visibility, identify two geostationary satellites with matching trajectories, confirm equinoctial visibility conditions, and classify case as Category A.

Female resident of La Bouëxière who promptly reported her observation, provided video evidence, and completed official questionnaire. Demonstrated responsible reporting behavior.
"Le point lumineux, plus gros et plus lumineux qu'une étoile... apparait au nord-ouest et traverse le ciel avec une trajectoire linéaire descendante et une vitesse qui semble constante."
04 Analyst Notes -- AI Processed
This case exemplifies the importance of astronomical context in UFO investigation. The witness's credibility is enhanced by immediate reporting, submission of supporting materials, and the detailed description provided. The observation occurred during a known period when geostationary satellites become visible—the weeks surrounding equinoxes when solar illumination angles allow these typically invisible objects to reflect sufficient sunlight for naked-eye detection. GEIPAN's methodical elimination of the ISS followed by identification of two geostationary satellites with matching trajectories demonstrates professional investigative rigor. The case presents minimal strangeness factors: no unusual maneuvers, color changes, sound, or physical effects were reported. The linear trajectory, constant velocity, and horizon-to-horizon transit are entirely consistent with orbital mechanics. The witness's description of the object as 'larger and brighter than a star' aligns with how satellites appear during optimal viewing conditions. The unusable video quality, while unfortunate, is understandable given handheld mobile phone filming in pre-dawn darkness. The single-witness testimony and lack of corroborating reports further support the mundane explanation. This case serves as an educational example of how uncommon astronomical phenomena can generate genuine UFO reports from credible observers unfamiliar with satellite visibility patterns.
05 Theory Comparison
BELIEVER ANALYSIS
Inadequate Investigation of Anomalous Characteristics
While the satellite explanation addresses basic trajectory and timing, some might argue that the witness's description of the object being 'larger and brighter than a star' warrants more scrutiny. The unusable video evidence means we cannot independently verify the object's appearance. A truly thorough investigation would require additional witnesses or verification that geostationary satellites at that distance would actually appear as described. However, this stance faces significant challenges given the perfect match of all other observed characteristics with satellite behavior.
SKEPTIC ANALYSIS
Conventional Satellite or Aircraft
Even without the detailed astronomical analysis, the observation characteristics strongly suggest a conventional explanation. The five-minute linear transit, constant velocity, horizon-to-horizon path, and steady white light are classic signatures of either satellite or high-altitude aircraft passage. The single witness, absence of unusual behavior, and timing during twilight hours when satellites are commonly visible all point to misidentification of a mundane aerial object.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a misidentification of a geostationary satellite during a period of optimal visibility near the autumnal equinox. The confidence level in this explanation is very high—GEIPAN's Category A classification represents their highest certainty of identification. Every aspect of the sighting aligns perfectly with known satellite characteristics: duration, trajectory, appearance, timing, and astronomical conditions. The witness observed a real phenomenon but misinterpreted it due to unfamiliarity with the temporary visibility of geostationary satellites during equinoctial periods. This case has no significance as an unexplained phenomenon but serves valuable purpose as a documented example of how seasonal astronomical conditions can create unfamiliar visual experiences for ground observers, contributing to the body of knowledge used to identify similar future reports.
