Sighting in Conflans-Sainte-Honorine, July 1, 2012

At around 11 p.m., a witness saw several orange lights pass by without a sound. They followed a slightly curved path toward the east, then abruptly changed course to head north and quickly disappeared.

The GEIPAN found that this description matched the passage of Thai lanterns in every respect: orange color, a smooth and silent drift with the wind, and disappearance after a few minutes. The weather data show a weak, variable wind from the southwest toward the northeast, and it was dying down. The GEIPAN did not look for the place where the lanterns might have been released; it only raised, as a question, the priory park at the end of a festival. The case is classified B: probable observation of Thai lanterns.
