An account in Haut-Rhin, France

On March 9, 2013 at 11:15 PM, a witness on their terrace is intrigued by the silent passage across the sky of several yellow glowing balls. This observation report has all the characteristics of an observation of Thai lanterns: glowing objects, yellow (more often described as yellow-orange), moving in more or less organized groups, moving according to the local wind (southwest to west: see Infoclimat data), crossing the sky in a few minutes, on a Saturday evening in an urban area. Given the low strangeness of this case, and given the density of housing in the vicinity, it was not deemed reasonable to search for the person who released them. Although the witness did not confirm this hypothesis, the GEIPAN sees no element in the testimony contrary to this hypothesis, and classifies this case "B" probable observation of Thai lanterns.
