On January 28, 1989, at approximately 20:30 hours, the Gendarmerie Nationale groupement (regional command) in Guéret, Creuse Department, issued an unusual directive to all its brigades: observe a particular phenomenon in the eastern sky. Multiple gendarmerie units across the department reported observing highly scintillating points of light displaying varied colors. The phenomenon was sufficiently notable that it prompted coordinated observation across multiple law enforcement stations, suggesting initial concern about a potential aerial anomaly or security matter.
The observations continued over several consecutive evenings, with gendarmerie personnel repeatedly witnessing the same multicolored, highly luminous scintillating points in the eastern sky. The consistency of the reports across multiple nights and multiple observation posts initially suggested a recurring aerial phenomenon worthy of official attention. However, GEIPAN's investigation quickly determined the astronomical nature of the sightings.
The case was classified as 'A' by GEIPAN, indicating a phenomenon with certain identification. The investigation concluded that the observations were caused by stellar scintillation—the twinkling of stars intensified by favorable meteorological conditions. Atmospheric turbulence, temperature inversions, or unusual humidity levels can cause stars to scintillate more dramatically than normal, creating the appearance of multicolored flashing lights that can be mistaken for anomalous phenomena, even by trained observers.

04 Analyst Notes -- AI Processed
This case demonstrates an important principle in UAP investigation: even trained, professional observers such as gendarmerie officers can be deceived by atmospheric optical effects. The fact that the phenomenon was observed 'plusieurs soirs de suite' (several evenings in a row) actually supports the astronomical explanation, as stellar positions would remain consistent relative to the observation time and direction. The eastern sky direction is particularly significant—this would have included bright stars rising in the evening, which are especially prone to scintillation when viewed near the horizon through denser atmosphere.
The credibility of the witnesses is actually quite high—these were multiple gendarmerie brigades, meaning professional law enforcement personnel trained in observation and reporting. However, this also illustrates that professional training does not necessarily include astronomical knowledge. The coordinated observation request from the Guéret command suggests initial uncertainty about the phenomenon's nature, indicating appropriate caution. The meteorological conditions mentioned in the conclusion (favorable for scintillation) likely involved atmospheric instability, possibly associated with weather front activity common in the Limousin region during winter months. This case serves as an excellent example of how GEIPAN's classification system works—thorough investigation leading to definitive explanation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Misidentification Enhanced by Observer Expectation
From a skeptical psychological perspective, once the initial observation directive was issued by command, subsequent observers may have experienced confirmation bias—looking for something unusual and therefore interpreting normal stellar scintillation as anomalous. The fact that professional observers initially found the phenomenon 'particular' enough to warrant coordinated observation demonstrates how context and expectation can influence perception of ordinary astronomical phenomena.
06 Verdict
ANALYST VERDICT
This case is definitively explained as astronomical misidentification due to enhanced stellar scintillation under specific atmospheric conditions. Confidence level: very high. GEIPAN's 'A' classification indicates certainty in this conclusion. While the case involves credible witnesses from law enforcement and multiple observation points, the explanation is straightforward and well-supported by the evidence: consistent eastern sky observations over multiple evenings, multicolored scintillating lights (characteristic of atmospheric refraction of starlight), and documented favorable meteorological conditions. The significance of this case lies not in any genuine anomaly, but as a valuable training example demonstrating how atmospheric phenomena can create convincing illusions even for professional observers, and how systematic investigation can resolve such reports conclusively.
