White lights above a roof in Essonne

Summary

On April 9, 2011, two witnesses in a car briefly saw white lights that seemed to be emitted by a dark object near the roof of a nearby house. The object moved very slowly and silently, which caught the attention of the witnesses. After it disappeared behind the roof, they got out of the car to look for it, but without success. The GEIPAN analyzed the case and ruled out explanations such as meteors, satellites, or aircraft. However, due to the lack of precise details, the case was classified as C. The lights could have been of a traditional type, such as Thai lanterns, although these are usually warm-colored.
