Multicolored UFO Seen in Essonne in 2015

Summary

On December 24, 2015, three people from the tenth floor of an apartment in Essonne observed for 45 seconds a colorful object changing colors between green, blue, and orange. The object moved silently and disappeared behind the building as it passed over the witnesses. Although only one testimony was collected, the description of a multicolored object flying at low altitude on a festive night initially suggested a lighter-than-air balloon. Meteorological data from Orly indicated a southwesterly wind, consistent with the object's movement. Ultimately, the GEIPAN classified the case as "B," likely attributing it to a festive LED balloon, a phenomenon that is becoming increasingly common.
