On January 13, 1978, at approximately 17:40 (5:40 PM), a female motorist in Guipel, Ille-et-Vilaine, observed a slow-moving luminous rectangular phenomenon in the sky with an orange-red coloration. The object featured distinctive halos on its longer sides. Her husband subsequently observed the same phenomenon. The sighting occurred during winter conditions with some cloud cover present, and no sound was heard during the observation period. The gendarmerie investigation found no ground traces and collected no additional witness testimonies beyond the married couple. GEIPAN's investigation established that the witnesses were credible and sincere, with their descriptions being precise and consistent. The phenomenon was observed moving slowly across the sky in the direction where the sun had just set below the horizon. The rectangular shape, orange-red color, duration of observation, and the presence of halos on the sides matched the characteristics of an atmospheric optical phenomenon. This case underwent re-examination by GEIPAN and was classified as 'PAN A' (identification certain) - a misidentification with a solar pillar. The investigators concluded that the witnesses' visual perception was accurate, but their interpretation of what they observed was influenced by the rarity of the phenomenon and their emotional response to witnessing an unusual atmospheric event. The winter season and partial cloud cover created ideal conditions for observing a solar pillar phenomenon.
02 Timeline of Events
17:40
Initial Sighting by Motorist
Female motorist observes slow-moving rectangular luminous phenomenon in the sky, orange-red in color with halos on the longer sides.
17:40+
Corroborating Observation
Witness's husband observes the same phenomenon, providing independent confirmation of the sighting details.
17:40 (concurrent)
Silent Observation Period
Throughout the observation, witnesses note complete absence of any sound associated with the phenomenon.
Post-event
Gendarmerie Investigation
Local gendarmerie conducts investigation, searches for ground traces (none found), and canvasses for additional witnesses (none located beyond the couple).
Post-investigation
GEIPAN Re-examination
Case undergoes renewed examination by GEIPAN, analyzing atmospheric conditions, sun position, and witness descriptions against known phenomena.
Final
Classification as PAN A
GEIPAN classifies case as PAN A (certain identification) - misidentification with solar pillar phenomenon. Low strangeness, explained.
03 Key Witnesses
Anonymous Witness 1
Motorist (female)
high
Female driver who first observed the phenomenon while traveling. GEIPAN noted her sincerity and credibility were never questioned during the investigation.
"Description of a slow-moving rectangular luminous phenomenon with orange-red coloration and halos on the longer sides."
Anonymous Witness 2
Civilian (husband of primary witness)
high
Husband of the primary witness who subsequently observed the same phenomenon. His account corroborated his wife's description.
"Confirmed observation of the rectangular luminous phenomenon with consistent details."
04 Analyst Notes -- AI Processed
This case represents a textbook example of credible witnesses misinterpreting a rare but natural atmospheric phenomenon. GEIPAN's assessment highlights several key factors supporting the solar pillar explanation: the timing coincided precisely with sunset, the observation direction aligned with the sun's position below the horizon, the rectangular shape with lateral halos matches solar pillar characteristics, and the winter conditions with partial clouds are optimal for such phenomena. The investigators specifically noted that witness credibility was never questioned - both individuals accurately described what they saw, but lacked the scientific knowledge to identify the phenomenon. The investigation's thoroughness is evident in the gendarmerie's search for ground traces and additional witnesses, though none were found. The absence of sound during the observation further supports the atmospheric explanation rather than a mechanical object. This case demonstrates low strangeness (étrangeté faible) as classified by GEIPAN - unusual enough to warrant reporting and investigation, but readily explainable through known natural phenomena. The case serves as an educational example of how even credible, detailed witness accounts can result from misidentification when observers encounter rare meteorological optics.

BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Rare But Natural Atmospheric Optics
This represents a straightforward case of witness unfamiliarity with uncommon atmospheric phenomena. Solar pillars, while natural, are rarely observed and can appear striking to those who encounter them. The complete absence of anomalous features (no sound, no physical traces, no radar contacts, no additional witnesses) combined with perfect alignment of timing and atmospheric conditions makes any alternative explanation unnecessary. The case demonstrates how even credible witnesses can report 'extraordinary' sightings that are entirely conventional phenomena.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a solar pillar observation. The convergence of multiple factors - precise timing at sunset, correct directional alignment, matching visual characteristics (rectangular shape, orange-red color, lateral halos), appropriate atmospheric conditions, and absence of anomalous features like sound or physical traces - provides overwhelming evidence for this conclusion. GEIPAN's 'A' classification indicates certainty in this identification. While the witnesses were reliable and their observation accurate, they simply encountered a rare atmospheric optical phenomenon unfamiliar to most people. This case holds minimal significance for anomalous phenomena research but serves valuable educational purpose in demonstrating how natural events can appear extraordinary to observers lacking specialized knowledge of atmospheric optics.
