🇫🇷 GEIPAN / CNES
At 6:40 AM on December 10, 1978, several witnesses—including gendarmes—observed a luminous phenomenon in the western sky displaying a pendular, ascending movement. The light remained visible for several hours, gradually fading until it disappeared around 9:30. Observers initially thought of Venus, but the object's unusual behavior raised doubts.
GEIPAN classified the case as A, finding no conventional explanation. The presence of law enforcement among the witnesses and the extended duration of the observation make this a notable entry in the record.
