On January 27, 1978, at approximately 17:45 (5:45 PM), a couple (designated T1 and T2) residing in Saint-Ciers-d'Abzac in the Gironde department observed a strange object in the sky through the windows of their home. The phenomenon appeared as a flat, oval-shaped object with a pale red color, seemingly hovering in place in the direction of the neighboring commune of Guitres. After 4-5 minutes of observation, the object appeared to accelerate and then disappeared from view in the sky. A third independent witness also reported observing the phenomenon.
The sighting prompted an official investigation by the Gendarmerie between January 29 and February 3, 1978, covering the local area and neighboring communes. Subsequently, GEPAN (the predecessor to GEIPAN) dispatched two CNES investigators who arrived on-site on April 12, 1978. Their initial assessment classified the case as 'D' (unexplained), and this classification remained in the GEIPAN database for years. However, the head of GEPAN at the time completed a supplementary report that reclassified the case as 'A' (identified), which the current GEIPAN describes as "a lesson in scientific ufology."
The case demonstrates the importance of thorough astronomical cross-referencing in UFO investigations. Despite the witnesses' sincere testimony and the consistency of their accounts, detailed analysis revealed that the observed phenomenon matched the characteristics of the planet Mars, which was positioned very close to the indicated axis of observation. The pale red color, the duration of observation, the apparent shape, and the hovering behavior were all consistent with Mars as viewed under atmospheric conditions at that time and location.

04 Analyst Notes -- AI Processed
This case represents an excellent example of proper scientific methodology in UFO investigation and the importance of astronomical data correlation. The credibility of all three witnesses was never questioned by investigators, and the consistency of their independent testimonies (particularly the presence of a third witness independent from the couple) initially suggested a genuine anomalous phenomenon. The fact that experienced CNES investigators initially classified this as 'D' (unexplained) demonstrates how convincing celestial misidentifications can be, even to trained observers.
The reclassification from 'D' to 'A' highlights several key factors: the pale red color is consistent with Mars's appearance, the apparent hovering matches the planet's slow apparent motion, the oval shape aligns with atmospheric distortion effects, and most critically, astronomical calculations confirmed Mars was positioned along the exact azimuth reported by witnesses. The 'acceleration and disappearance' described by witnesses likely corresponds to atmospheric effects or the planet setting below the horizon or cloud cover. The case file notes this as a 'lesson in scientific ufology,' emphasizing that witness credibility alone is insufficient without eliminating prosaic explanations through rigorous astronomical analysis.
05 Theory Comparison
BELIEVER ANALYSIS
Genuine Anomalous Object (Initial Assessment)
The initial GEPAN investigators classified this as 'D' (unexplained) based on the consistency of three independent witnesses, the credibility of all observers, and the described behavior (acceleration and disappearance). The witnesses were deemed sincere and their descriptions precise, suggesting a genuine anomalous aerial phenomenon rather than a conventional explanation.
SKEPTIC ANALYSIS
Atmospheric Optical Effects
Even if the Mars identification had not been confirmed, the characteristics described (pale red color, oval shape, apparent motion) are consistent with atmospheric distortion and optical effects on celestial objects viewed through Earth's atmosphere, particularly near the horizon at twilight hours (17:45 in late January).
06 Verdict
ANALYST VERDICT
This case is conclusively explained as a misidentification of the planet Mars. Despite the initial mystery and the consistency of multiple witness testimonies, thorough astronomical analysis demonstrated that Mars was positioned precisely where witnesses reported seeing the phenomenon, exhibiting characteristics (color, apparent size, duration of visibility) that matched the observations. The GEPAN director's supplementary report correctly reclassified this from unexplained to identified, providing an important case study in the necessity of cross-referencing witness reports with astronomical data. While the witnesses were sincere and their observations consistent, this case demonstrates that even trained investigators can initially misclassify sightings when astronomical factors are not immediately considered. The case holds educational value as an example of proper scientific methodology prevailing over initial impressions.
