An account in Savoie, France

On February 28, 2009, between 6:30 PM and 7:35 PM, people at a ski resort noticed, from different locations, the presence of two lights of spherical shape but different sizes. The observations were made at a significant distance, but the witnesses noted the movement of these bright spheres in the mountain range. Many photos and videos of the phenomenon were taken before the lights disappeared. This observation was reported very late to GEIPAN (March 4, 2011) through a questionnaire and a very large number of photos. Without conducting an in-depth investigation, the reconstruction of the observation from 2 of the photos (IMG_0114 and IMG_0105) places the phenomenon ("2 luminous balls") on the mountainside at the level of the ski slopes. The observation period corresponds to the peak ski season. The hypothesis that what was observed was the headlights/spotlights (one of the 2 balls) of a ski slope grooming machine (snowcat) and an inflatable illuminated balloon (a technique commonly used) is probable.
