Cylindrical object with dome over Seine-Maritime marshes in 1989

Summary

On January 12, 1989, a woman driving through Seine-Maritime observed a cylindrical object hovering about thirty meters above the marshes. Its upper section featured a dome emitting yellow light, while its base displayed a series of bright red and white windows. As the witness passed nearby, the object went dark momentarily before reappearing higher in the sky. The observation lasted only a few seconds. Subsequent investigations failed to identify the phenomenon or gather any additional information.
