Reddish Ball in the Sky over Argenteuil

Summary

On July 13, 1979, around 11:30 PM, several witnesses in Argenteuil noticed an object in the sky that caught their attention. It was a ball the size of a soccer ball, with an orange-red color, moving at high altitude. During the observation, the object changed shape and color, stopped momentarily, and then sped away at an impressive speed, disappearing into the atmosphere. The witnesses could not identify the phenomenon with conventional objects. Despite the detailed description, no other testimonies or plausible explanations were obtained, leaving the case unresolved.
