An account in Haute-Savoie, France

On July 12, 2014, at around 11:50 PM, a motorist and his passenger observed the silent passage of 7 to 8 luminous objects in the sky, yellow-orange in color. The witness had time to take photographs. The observation of yellow-orange balls crossing the sky in a few minutes, on a weekend night, clearly suggests Thai lanterns, probably released nearby at the end of a private party. The photos taken by the witness are entirely consistent with this hypothesis. The movement was observed from North to South. The Geneva weather report indicates a weak, unstable wind (from the North at 9 PM, from the West at 10 PM, from the South at 11 PM, from the Southwest at midnight). Moreover, in mountainous areas, very local winds are complex at the end of the day: it is unfortunately not possible to determine the local wind precisely after the fact, in order to confirm or not whether these flying objects were carried by the wind. GEIPAN classifies this case "B": probable observation of Thai lanterns. See the Meteociel report from the day of the observation.
