On September 13, 2022, at approximately 21:00 hours, a single witness observed an unusual white luminous point from their garden in Ruffec, Charente department, France. The object exhibited highly distinctive cyclic behavior: it moved in an arc pattern toward the west, appearing and disappearing in a repetitive cycle at the same location in the sky. Each appearance-disappearance cycle lasted approximately 6 seconds and repeated continuously throughout the observation period. After approximately 5 minutes of this cyclic behavior, the object made a slight displacement downward and toward the west-southwest before disappearing permanently.
The French space agency GEIPAN conducted a thorough investigation, classifying this case as 'D' (unidentified phenomenon after investigation) - their most enigmatic category. GEIPAN rated the case consistency as "medium" due to the single witness and absence of photographic or video evidence. However, the witness description was detailed and specific, providing sufficient information for investigators to explore multiple hypotheses. The witness compared the luminous point to aircraft position lights, noting its white color and precise, repetitive motion pattern.
What makes this case particularly notable is GEIPAN's systematic elimination of conventional explanations. Investigators explored four primary hypotheses: commercial aircraft, Starlink satellite flares, skytracer light projections, and atmospheric ice crystal reflections. Each hypothesis was methodically tested against the observation parameters and environmental conditions. The persistence of the unexplained cyclic behavior after rigorous scientific investigation, combined with official classification as unidentified by a credible government agency, elevates this case beyond typical misidentification reports.
02 Timeline of Events
21:00
Initial Observation
Witness in garden of residence in Ruffec observes a white luminous point toward the west. Object begins exhibiting cyclic arc-pattern movement.
21:00-21:05
Cyclic Behavior Phase
Object performs repetitive cycles of appearance and disappearance at the same sky location. Each cycle lasts approximately 6 seconds. Movement follows arc pattern. Witness notes resemblance to aircraft position lights.
~21:04
Directional Shift
Object makes a slight displacement downward and toward west-southwest direction, breaking from its previous fixed-location cycling pattern.
~21:05
Final Disappearance
After approximately 5 minutes of total observation time, the luminous point disappears permanently. No reappearance observed.
Post-incident
GEIPAN Investigation Initiated
French space agency GEIPAN opens official investigation. Case assigned ID 2022-09-51395. Investigators conduct air traffic reconstruction, satellite tracking analysis, and meteorological assessment.
Post-investigation
Classification as 'D' - Unidentified
After systematic elimination of four major hypotheses (aircraft, Starlink flares, skytracer projections, ice crystal reflections), GEIPAN classifies case as 'D' - phenomenon not identified after investigation. Strong residual strangeness noted due to repetitive behavior.

Anonymous Witness 1
Civilian resident
medium
Single witness observing from their garden in Ruffec. Provided detailed temporal and directional information, including specific estimates of elevation angles, duration of cycles, and directional changes. No background information available, but observation details suggest competent observational skills.
"The luminous point resembled aircraft position lights, moving in an arc pattern with regular 6-second cycles of appearance and disappearance at the same sky location."
04 Analyst Notes -- AI Processed
This case demonstrates the value of systematic scientific investigation by official agencies. GEIPAN's methodology reveals a thorough approach: air traffic reconstruction confirmed numerous aircraft passed through the observed trajectory, yet the rhythm and frequency of the cyclic appearances significantly exceeded actual aircraft passages. The Starlink flare hypothesis initially appeared promising - the witness description of the object's appearance matched these phenomena. However, geometric analysis proved incompatible: the sun's position at -29° below the horizon was at the threshold limit (required: -30° to -45°), positioned northwest (~312° azimuth) while the observation faced west. Most critically, the witness estimated the object's elevation between 45° and 60°, far exceeding the maximum 5° elevation required for Starlink flares.
The elimination of skytracer projections (no confirmed mid-level cloud layer to serve as projection surface) and ice crystal reflections (high-altitude winds too strong for crystal formation and stable positioning) demonstrates rigorous analysis. The case's classification as 'D' with "strong residual strangeness" is significant - GEIPAN reserves this classification for cases where investigation yields no conventional explanation. The repetitive behavior pattern (6-second cycles over 5 minutes) represents the core anomaly. This precision and consistency suggests either an unknown natural phenomenon with predictable periodicity, or controlled artificial behavior. The witness credibility cannot be fully assessed from available data, but their detailed observations and the ability to estimate timing, direction, and elevation suggest a competent observer.
05 Theory Comparison
BELIEVER ANALYSIS
Unconventional Aerial Phenomenon - Possible Non-Human Technology
The characteristics that make this case resistant to conventional explanation - precise 6-second cycles, fixed position cycling, sudden directional shift, then permanent disappearance - align with reported behaviors of structured craft exhibiting intelligent control. The cyclic appearance-disappearance could represent: rotation of a craft with intermittent reflective surfaces; periodic energy field activation; dimensional phasing; or scanning/surveillance patterns. The fact that GEIPAN, a credible scientific organization, could not identify the phenomenon after systematic investigation lends significant credibility. The behavior appears purposeful rather than random, suggesting possible observation or data collection activity. The slight downward and southwest displacement before final disappearance could indicate deliberate departure after completing an objective. France's airspace monitoring and GEIPAN's access to military radar data make conventional explanations even less likely to have been overlooked.
SKEPTIC ANALYSIS
Misperceived Aircraft with Confirmation Bias
The most parsimonious explanation remains misperceived aircraft despite GEIPAN's analysis. Air traffic reconstruction confirmed numerous aircraft on the observed trajectory. The witness may have conflated multiple aircraft passages into a single phenomenon, or misjudged timing intervals due to attention lapses. The 'cyclic' pattern could result from aircraft turning at similar waypoints, causing lights to appear, disappear behind wings or fuselage during banking maneuvers, then reappear. The witness's comparison to 'aircraft position lights' supports this. Single-witness observations without corroboration are notoriously unreliable for precise timing and spatial measurements. The 6-second cycle estimate may be inaccurate, and the apparent repetition at the 'same location' could reflect misperception of depth and distance for multiple objects following similar flight paths.
06 Verdict
ANALYST VERDICT
This case remains genuinely unidentified after professional investigation by France's official UAP research organization. GEIPAN's 'D' classification carries significant weight - representing cases where thorough investigation fails to identify conventional explanations. The cyclic behavior pattern is the defining mystery: no known natural or artificial phenomenon convincingly explains 6-second appearance-disappearance cycles repeated consistently over 5 minutes at a fixed sky position. While the single witness and lack of physical evidence limit the case's strength, the systematic elimination of aircraft, satellites, ground-based projections, and atmospheric phenomena by trained investigators prevents easy dismissal. This case exemplifies high-quality official UFO investigation methodology, even if it doesn't provide definitive answers. The most honest assessment is that the phenomenon remains unexplained - neither definitively extraordinary nor satisfactorily conventional. It deserves inclusion in UAP databases as an example of rigorous investigation yielding inconclusive results, demonstrating that some observations genuinely resist identification despite scientific scrutiny.
