Raincy (93) 2009, Luminous balls in the sky

Summary

On the night of October 31, 2009, a witness in Raincy (France) observed a strange phenomenon: several luminous spheres moving in an unusual way across the sky. The witness noticed how the lights approached, receded, and crossed each other, creating an actual "ballet" in the air. Curious, he woke up his partner, who also confirmed what she saw. Both continued to observe the phenomenon for several hours, until the witness decided to go back to sleep around five in the morning, while the show continued. Although the case was classified as low strangeness, the investigation suggested it could be the rotation of two sky trackers, devices that project laser beams into the sky. However, the exact location of the animation could not be confirmed, leaving a partially solved mystery.
