On May 19, 2008, a witness on the island of Groix in Brittany, France submitted a photograph to GEIPAN showing mysterious red spots that appeared anomalous. The witness reported these red stains on their photograph without initially understanding their origin. GEIPAN conducted a detailed photographic analysis to determine the nature of these anomalies.
The investigation revealed a textbook example of lens flare caused by internal reflections within the camera's optical system. The analysis demonstrated that three streetlamps visible in the photograph were creating internal reflections that manifested as red spots on the image. When investigators drew lines connecting each streetlamp to its corresponding red spot, all three segments intersected at a single point—the 'mirror point' of the phenomenon, which was positioned exactly at the center of the photograph corresponding to the lens's focal point.
GEIPAN noted that each red spot's intensity correlated directly with the distance and brightness of its corresponding streetlamp in the frame. The investigators characterized this as a particularly clear 'textbook case' of lens flare, likely due to the fortuitous positioning of the three streetlamps grouped around the optical center of the lens. This case was classified as 'A' by GEIPAN, indicating a phenomenon completely explained with certainty.
02 Timeline of Events

Witness Notices Anomalies
Upon reviewing the photograph, witness observes mysterious red stains/spots and decides to submit the image to GEIPAN for official investigation.
Post-submission
GEIPAN Receives Case 2008-05-02297
GEIPAN receives the photograph and opens an official investigation file for the reported anomalies.
During investigation
Geometric Analysis Performed
Investigators conduct detailed photographic analysis, connecting each streetlamp to its corresponding red spot. All three connecting lines intersect at the photograph's center point.
During investigation
Mirror Point Identified
Analysis reveals the intersection point is the 'mirror point' of the phenomenon, positioned exactly at the lens's focal point. Red spot intensities correlate with streetlamp distances.
Investigation conclusion
Case Classified as 'A' - Fully Explained
GEIPAN determines this is a textbook example of lens flare caused by internal reflections. The case is designated as educational reference material for identifying similar optical artifacts.

04 Analyst Notes -- AI Processed
This case represents an exemplary instance of GEIPAN's scientific methodology in debunking photographic anomalies. The geometric analysis performed—demonstrating that connecting lines between light sources and anomalies intersect precisely at the optical center—provides irrefutable proof of lens flare rather than any external phenomenon. The investigators' observation that spot intensity varies with streetlamp distance and brightness further confirms the internal reflection hypothesis.
The case has high educational value despite low anomaly value. GEIPAN's designation of this as a 'cas d'école' (textbook case) suggests it serves as a reference example for training investigators to recognize similar lens artifacts. The witness's willingness to submit the photograph and accept the explanation demonstrates good public engagement with the scientific investigation process. This case illustrates why photographic evidence requires careful analysis before drawing conclusions about anomalous phenomena.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Common Photographic Misidentification
While the witness initially perceived these red spots as potentially anomalous, they represent one of the most common sources of UFO photograph misidentifications. Lens flare is frequently misinterpreted by photographers unfamiliar with optical artifacts. The witness's willingness to submit the image for analysis and accept the scientific explanation demonstrates appropriate critical thinking. This case illustrates why photographic evidence alone, without understanding of camera mechanics and optics, cannot be considered reliable evidence of anomalous phenomena.
06 Verdict
ANALYST VERDICT
This case is definitively explained as camera lens flare caused by internal reflections of streetlamps. The geometric precision of the analysis—with all reflection vectors converging at the lens's focal point—leaves no room for alternative interpretation. GEIPAN's 'A' classification is entirely justified. While this case holds no significance for genuine UAP research, it serves valuable educational purposes in demonstrating how mundane optical phenomena can create convincing photographic anomalies. The case reinforces the necessity of rigorous photographic analysis in UFO investigations and provides investigators with a clear reference example for identifying similar lens artifacts in future cases.
