UFO seen in France, silent white ball

Summary

In July 2009, several witnesses in Saint-Just-Saint-Rambert (France) saw a white object in the sky. One of them described a white ball moving slowly and silently along a north-south trajectory through the valley. Suddenly, the object accelerated and climbed in altitude, disappearing into the sky. Although initially intriguing, the report suggests it could be a weather balloon, as its behavior and characteristics match those described by the witness.

The GEIPAN, the French organization responsible for investigating unidentified aerial phenomena, classified the case as category B, indicating a plausible but not definitive explanation. The lack of noise, the spherical shape, and the regular trajectory are elements that fit a balloon, although the possibility of an unusual phenomenon is not completely ruled out.
