On the evening of June 3 or 4, 2009, at approximately 19:00 hours, an amateur photographer in Seysses, Haute-Garonne, France, captured a photograph of the sky showing the Moon and what appeared to be white contrails from an aircraft. The witness did not notice anything unusual during the actual photography session. Two days later, while reviewing the photograph, the witness observed something anomalous that had not been visible to the naked eye during the exposure—what they described as 'parallel bars' in the image. The photograph showed luminous trails that created an unusual visual pattern. The witness was puzzled by the appearance of these parallel structures, which differed from the static appearance of typical jet engine contrails visible in the same frame. This discrepancy between what was observed in real-time versus what appeared in the photograph prompted the witness to report the incident to GEIPAN for official investigation. GEIPAN's investigation, conducted by France's official UFO research body (part of CNES, the French space agency), concluded with a Class A classification—the highest certainty rating indicating a fully explained phenomenon. The investigators determined that the witness had photographed a commercial airliner in motion during the exposure, creating the impression of parallel bars due to the aircraft's movement during the camera's shutter time. The apparent motion blur of the aircraft body contrasted with the relatively stationary appearance of the engine contrails, creating the optical illusion that concerned the witness.

Photograph Captured
Amateur photographer takes a photograph of the evening sky showing the Moon and aircraft contrails in Seysses, Haute-Garonne. Nothing unusual observed visually at the time of exposure
Two days later
Anomaly Discovered
Witness reviews photograph and notices 'parallel bars' pattern that was not visible during the original observation. The unusual appearance prompts concern and investigation
Investigation period
GEIPAN Investigation
GEIPAN conducts official analysis of the photograph and witness testimony. Technical examination of the image characteristics and comparison with known phenomena
Investigation conclusion
Class A Classification Issued
GEIPAN determines the parallel bars are caused by motion blur of a commercial airliner during camera exposure. The moving aircraft created parallel traces while contrails appeared stationary. Case classified as fully explained

04 Analyst Notes -- AI Processed
This case represents a textbook example of photographic artifact misidentification and demonstrates the value of official investigation processes. The witness credibility is reasonable—an amateur photographer with enough technical knowledge to question what appeared in their image, yet unfamiliar with motion blur effects in long exposures. The two-day delay before reviewing the photograph is a significant detail, as it indicates the witness was not actively searching for anomalies but genuinely discovered something unexpected. The GEIPAN investigation's Class A conclusion is highly credible. The 'parallel bars' effect is consistent with a moving aircraft captured during an exposure time long enough to record both the aircraft's position changes and the persistent contrails. The witness's observation that contrails appeared 'immobile' while the aircraft left parallel traces perfectly aligns with exposure-related motion capture. The time of day (19:00 in early June) places this during dusk with good lighting conditions for both the Moon and aircraft, explaining why both features are visible. No corroborating witnesses, radar data, or additional evidence exists, as expected for a conventional aircraft photograph.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Photographic Artifact Misidentification
The witness, while competent enough to take photographs, lacked understanding of how camera exposure settings affect moving subjects. The two-day delay before reviewing the image meant no immediate correlation with observed aircraft could be made. The 'parallel bars' are simply motion blur, a common occurrence in amateur photography when shutter speeds are too slow for the subject's movement. No anomalous phenomenon occurred—only a misunderstanding of photographic principles.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a photographic capture of a commercial airliner in flight, with the 'parallel bars' phenomenon resulting from motion blur during camera exposure. The GEIPAN Class A classification is fully justified. The apparent anomaly demonstrates how camera technology can record phenomena differently than human perception, creating misleading visual artifacts. This case has minimal significance for UAP research but serves as an excellent educational example of how conventional phenomena can appear anomalous when captured through photographic equipment, particularly when exposure settings are not optimized for moving subjects. The witness's honest reporting and GEIPAN's thorough analysis exemplify proper investigation protocols.
