Mylar Balloon Sighting in Paris 2015

Summary

On May 4, 2015, at 10:05 AM, a witness in Paris observed a slowly moving, shimmering object in the sky. The object displayed changing reflections and appeared unusual enough to be documented. Despite being in daylight, the witness took photographs of the event. After analysis, the GEIPAN classified the case as "B"—likely a child's Mylar balloon. These metallic balloons, when released, spin and reflect light in unpredictable ways, making them difficult to track. The lack of additional reports or precise trajectory data made it impossible to confirm the exact path, but the description and images strongly suggest a common party balloon rather than an unidentified flying object.
