On October 24, 1977, between 17:15 and 18:00 hours, three residents of Guise in the Aisne department of France independently observed what they described as a red or fiery sphere at the horizon from which sparks or flames appeared to disperse. The phenomenon was visible for five to ten minutes before gradually disappearing below the horizon. Concerned by what they had witnessed, the witnesses filed reports with the local gendarmerie on October 25 and 27, leading to an official investigation.
The case attracted local media attention, with an article appearing in the newspaper L'Union on October 26, 1977. Gendarmes conducted multiple patrols over several consecutive days but found no anomalous phenomena and collected no additional witness testimony. The witnesses' sincerity and credibility were never questioned by investigators, and the description of the object was considered reasonably precise and consistent across all three accounts.
Originally classified as a "C" case (unidentified), GEIPAN later re-examined this sighting using improved analytical software and accumulated investigative experience. The re-investigation determined that the phenomenon displayed characteristics entirely consistent with the setting sun: the observed duration, spherical form, apparent size, red/fiery coloration, and directional axis all matched astronomical calculations for sunset on that date at that location. GEIPAN concluded this was a case of misidentification where witnesses correctly perceived a real phenomenon but misinterpreted its nature due to their emotional response of astonishment. The case was reclassified to "A" (explained with certainty) as a misidentification of the setting sun.
02 Timeline of Events
1977-10-24 17:15-18:00
Initial Observation Begins
Three separate residents of Guise observe a red or fiery spherical object at the horizon with apparent sparks or flames dispersing from it. Exact observation times varied slightly between witnesses.
1977-10-24 17:20-18:10
Phenomenon Visible for 5-10 Minutes
Witnesses observe the phenomenon for five to ten minutes. The object appears stationary or slowly moving along the horizon, maintaining its red/fiery appearance throughout.
1977-10-24 17:25-18:15
Object Gradually Disappears
The phenomenon progressively disappears below the horizon, consistent with the setting sun descending below the visible horizon line.

GEIPAN Re-examination and Reclassification
GEIPAN re-examines the case using modern analytical software and accumulated investigative experience. Astronomical calculations confirm sun position matched witness descriptions exactly. Case reclassified from C (unidentified) to A (explained with certainty) as sunset misidentification.
03 Key Witnesses
Anonymous Witness 1
Civilian resident of Guise
high
One of three Guise residents who filed reports with gendarmerie. GEIPAN investigators noted witness credibility and sincerity were never in doubt.
Anonymous Witness 2
Civilian resident of Guise
high
Second witness who independently reported the same phenomenon. Filed gendarmerie report on October 25 or 27.
Anonymous Witness 3
Civilian resident of Guise
high
Third witness corroborating the observation. All three witnesses provided consistent descriptions of the phenomenon.
04 Analyst Notes -- AI Processed
This case represents a textbook example of how psychological factors can influence the interpretation of ordinary phenomena. The witnesses were credible individuals who accurately observed and described what they saw—the issue was not their perception but their interpretation. The setting sun, particularly under certain atmospheric conditions, can appear unusually large, red, and display apparent "sparks" or distortions due to atmospheric turbulence and scattering effects. The timing (evening hours between 17:15-18:00 in late October), duration (5-10 minutes matching typical sunset observation periods), color (red/fiery), and directional axis all align precisely with astronomical sunset data.
The strength of this case lies in GEIPAN's thorough re-examination methodology. Originally classified as "C" (unidentified), the case benefited from modern analytical tools and decades of accumulated investigative experience. The fact that gendarmes found no physical evidence, no additional witnesses came forward despite media coverage, and that astronomical calculations definitively placed the sun in the exact position described by witnesses provides compelling evidence for the misidentification hypothesis. This case demonstrates that even multiple credible witnesses can collectively misinterpret a phenomenon when it presents unusually or unexpectedly, particularly when filtered through emotional responses like surprise or astonishment.

BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Psychological Interpretation Bias
This case demonstrates how cognitive biases and emotional responses can transform mundane observations into extraordinary experiences. The witnesses' 'étonnement' (astonishment) colored their interpretation of what was actually an ordinary sunset. Once the first witness interpreted the setting sun as something unusual, confirmation bias may have influenced others to perceive it similarly. The fact that no additional witnesses came forward despite media coverage, and that gendarmes observed nothing unusual during subsequent patrols, suggests the phenomenon was not objectively extraordinary. The delay between observation (October 24) and some reports (October 27) allowed time for witnesses to discuss and potentially influence each other's accounts. This case serves as a cautionary example of how witness reliability relates to perception accuracy, not interpretation accuracy.
06 Verdict
ANALYST VERDICT
GEIPAN's conclusion of misidentification with the setting sun is virtually certain and well-supported by evidence. The astronomical data is irrefutable: the sun was setting in precisely the direction and timeframe described by all three witnesses. Every characteristic of the observed phenomenon—color, shape, duration, apparent movement, and gradual disappearance—matches known sunset behavior. This case holds minimal significance as a UFO event but serves valuable purpose as a training example for investigators on how atmospheric optics, psychological interpretation, and witness emotion can transform a mundane astronomical event into an apparently mysterious phenomenon. The case exemplifies GEIPAN's commitment to rigorous re-examination and demonstrates the value of applying improved analytical methods to historical cases.
