An account in Haut-Rhin, France

This high-quality testimony describes the observation at 10:59 PM of a group of white lights (about fifteen or so) silently crossing part of the sky in one minute. The witness describes the progressive disappearance of the phenomenon; this testimony suggests the observation of glowing balloons or Thai lanterns carried by the wind, probably released nearby at the end of a private party. The movement is observed from East to West (see the witness's diagram). The wind recorded at Colmar at 11 PM is light, from the North sector (Northeast a bit earlier): the weather is roughly compatible with this movement; the variability of the wind at low altitude, and the impossibility for the witness to judge the distance or approach of the lights over such a short time, may explain this directional discrepancy. GEIPAN classifies this case "B": probable observation of Thai lanterns or glowing balloons carried by the wind.
