On the evening of March 13, 1989, between 22:30 and 23:28 hours, multiple witnesses across two French departments—Morbihan (56) and Yvelines (78)—reported observing an extensive luminous phenomenon within cloud layers. Witnesses described highly varied colors including yellow, green, and red lights of significant magnitude spreading across the sky. The sightings were reported to local gendarmeries, who conducted initial investigations across both regions, separated by approximately 400 kilometers. The local gendarmerie investigators connected the phenomenon to a solar eruption that had occurred during the same period and had been widely reported in media outlets. The observed characteristics—duration, scale, and distinctive multi-colored display—matched known properties of auroral phenomena. GEIPAN's investigation confirmed that an aurora borealis was indeed exceptionally visible from mainland France on this specific date, a rare occurrence happening approximately once per decade at these latitudes. Originally classified as Type B ("spectacular natural phenomenon of light propagation") by SEPRA in 1989, this case was subsequently reclassified to Type A (identified with certainty) following GEIPAN's systematic review of archived cases using improved analytical software and accumulated investigative experience. The reclassification reflects the definitive identification of the phenomenon as a confirmed aurora borealis observation, with the witness reports fully consistent with geomagnetic storm activity documented on that date.

04 Analyst Notes -- AI Processed
This case demonstrates the value of institutional memory and case review procedures. The witnesses' inability to immediately recognize the aurora borealis is entirely understandable given the rarity of such displays at mainland French latitudes (approximately 47-49°N). The fact that multiple independent witnesses across two departments separated by hundreds of kilometers reported similar phenomena with consistent timing (22:30-23:28) and characteristics (yellow, green, red coloration) strongly corroborates the astronomical explanation. The gendarmerie's investigative work linking the sightings to concurrent solar activity shows appropriate scientific reasoning. The March 13, 1989 geomagnetic storm was indeed a significant event, caused by a coronal mass ejection that produced visible auroras at unusually low latitudes. GEIPAN's methodical reclassification from Type B to Type A exemplifies proper scientific protocol—the original classification as an unidentified natural light phenomenon was appropriate given 1989's investigative capabilities, but modern analysis and correlation with documented solar activity data now permits definitive identification. The case file explicitly notes the rarity factor, which explains witness unfamiliarity while strengthening confidence in the aurora explanation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Mass Misidentification of Natural Atmospheric Phenomenon
While the aurora explanation is correct, this case illustrates how even spectacular but natural phenomena can generate UFO reports when witnesses lack familiarity with rare atmospheric events. The initial uncertainty and witness reports to authorities demonstrate how extraordinary natural events can be misperceived as anomalous when outside normal experience. No alternative explanation is necessary or supported by evidence.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as an observation of aurora borealis during the exceptional geomagnetic storm of March 13, 1989. The witness descriptions, timing, geographic distribution, and correlation with documented solar activity leave no reasonable doubt. While the witnesses' reports might have initially suggested anomalous aerial phenomena, the multi-departmental nature of simultaneous sightings, characteristic auroral coloration, and confirmed solar storm activity provide a complete and scientifically sound explanation. This case holds minor significance primarily as a well-documented example of rare mid-latitude auroral activity and as a demonstration of effective case review procedures, but offers no evidence of unexplained phenomena. Confidence level: absolute certainty.
