ENQUETE 86 / 06 «L'AMARANTE» NOTE TECHNIQUE No 17

This technical note, issued by the GEPAN (Groupe d'Etude des Phénomenes Aérospatiaux Non-Identifiés) on March 21, 1983, details the investigation into a UAP sighting reported by a 30-year-old biologist, Monsieur Henri, in V1, France. On October 21, 1982, at approximately 12:35, the witness observed an ovoid, metallic object, approximately 1.5 meters in diameter and 0.8 meters thick, hovering one meter above his garden. The object, which had a blue-green upper section and a metallic lower section, remained stationary for 20 minutes before ascending vertically at high speed. The witness reported no sound, heat, or radiation. Following the event, the witness discovered that amaranth plants in his garden had withered. The Gendarmerie and later GEPAN investigators collected plant samples for biochemical analysis. The investigation included a detailed reconstruction of the witness's movements, meteorological data, and radar records from the CODA, which showed no significant anomalies. Biochemical analyses of the plants were conducted at the University Paul Sabatier, but results were inconclusive due to delays in sample preservation and handling. The report concludes that while the witness's account is consistent and credible, the physical evidence is insufficient to draw definitive conclusions. The investigators suggest that an intense electric field at the moment of the object's departure might explain the observed effects on the vegetation, but this remains a hypothesis. The document underscores the challenges of investigating such phenomena and the necessity for rigorous, standardized scientific protocols in future cases.
