On Thursday, December 17, 2009, at approximately 15:37, a witness photographed a snowy landscape in rapid succession from their 7th-floor apartment in Joué-lès-Tours, France. The witness observed nothing unusual during the photography session. Upon reviewing the images on their computer, they noticed an anomalous spot on one of the photographs that did not appear on the preceding or following frames.
The witness reported the anomaly to GEIPAN (Groupe d'études et d'informations sur les phénomènes aérospatiaux non identifiés), France's official UFO investigation unit operated by CNES (Centre National d'Études Spatiales). GEIPAN conducted a forensic analysis of the photograph using IPACO software, a specialized tool for analyzing photographic anomalies in UAP cases.
The IPACO analysis revealed parameters consistent with a small insect passing very close to the camera lens at high speed during the exposure. The estimated dimensions and velocity matched those of a Drosophila (common fruit fly). GEIPAN noted this case as typical of what they term 'rods' in ufology—photographic artifacts caused by insects captured in motion near the camera lens. The case was classified as 'A' (fully explained) and represents the type of case GEIPAN now processes rapidly or no longer investigates in detail.
02 Timeline of Events
15:37
Photographic Session Begins
Witness begins taking rapid succession (burst mode) photographs of snowy landscape from 7th-floor apartment window. No visual anomalies observed during photography.
15:37
Anomalous Frame Captured
Single photograph captures anomalous spot/shape. Witness does not observe anything unusual at the moment of capture. Object does not appear in preceding or following frames.
After 15:37
Discovery of Anomaly
During computer review of photographs, witness notices unusual spot on one image. Intrigued by the anomaly, witness decides to report to GEIPAN.
Post-incident
GEIPAN Investigation Initiated
Official investigation opened. Case assigned ID 2009-12-02517. Photograph submitted for technical analysis.
Post-incident
IPACO Software Analysis
Forensic analysis using IPACO software reveals parameters consistent with small insect very close to lens. Dimensions and estimated velocity match Drosophila characteristics.
Post-incident
Case Classification
GEIPAN concludes insect explanation (Drosophila/fruit fly) and assigns Classification A (fully explained). Case closed as typical 'rod' photographic artifact.

04 Analyst Notes -- AI Processed
This case exemplifies the importance of rigorous photographic analysis in UAP investigation. The witness's credibility is not in question—they accurately reported what they observed (an anomaly on a photograph) without making extraordinary claims. The key factor is that the anomaly was never seen with the naked eye, appearing only on photographic review, and was absent from sequential frames taken moments before and after.
The IPACO software analysis provided objective metrics that allowed investigators to determine the object's proximity to the lens and velocity. The 'rod' phenomenon has been thoroughly documented in photography and entomology: when insects fly very close to a camera lens during exposure, they appear as elongated, blurred anomalies due to motion blur. The fact that this occurred during winter (December, with snow visible) when insect activity is reduced but not absent indoors makes the drosophila explanation entirely plausible, as these insects commonly inhabit human dwellings year-round. GEIPAN's decision to classify this as 'A' and note it as representative of cases they now process expeditiously demonstrates mature investigative protocols that prioritize cases with genuine anomalous characteristics over photographic artifacts.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Camera Sensor or Lens Artifact
Alternative prosaic explanation could include a temporary sensor artifact, dust on the lens, or a water droplet that was briefly present given the snowy conditions. However, this is less likely than the insect explanation because such artifacts typically appear in multiple frames or have different characteristics. The IPACO analysis apparently ruled out these possibilities by measuring motion and dimensional characteristics inconsistent with static lens contamination.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as a photographic artifact caused by a small insect, most likely a Drosophila (fruit fly), passing extremely close to the camera lens during the exposure. The GEIPAN classification of 'A' (identified with certainty) is entirely appropriate. The case holds minimal significance for UAP research but serves educational value as an example of the 'rod' phenomenon—a photographic effect that has occasionally been misinterpreted in ufology. The rigorous application of IPACO analysis demonstrates proper investigative methodology, transforming sparse initial data into definitive conclusion through scientific analysis. This case underscores why witness reports of objects seen only in photographs, never visually, require special scrutiny and advanced analytical tools.
