Sighting in Romans-sur-Isère, January 1, 2015

On New Year's night, at 4:25 a.m., witnesses saw about twenty coloured balls of light in the sky, described in the investigation as orange. They moved silently and crossed the sky in a few minutes. Only one account was collected, and the witness filmed the scene on video.

The movement ran from north to south, which matches the north wind recorded by Météociel at Orange. GEIPAN considered that orange balls crossing the sky on a festive night strongly suggested Thai lanterns, most likely released nearby at the end of a private party, as often happens on New Year's night. The witness's videos left no doubt about this explanation.

The case was classified B: very probably Thai lanterns. The first observation described could also match a festive object carried by the wind, of a less common type than standard Thai lanterns.
