NOISY-LE-GRAND (93) 26.08.2024

On Monday 26 August 2024 at 11:40, a witness at work in Noisy-le-Grand (93) saw a black object remain stationary while rotating regularly for about 5 minutes. Sunlight reflected off it in intermittent flashes before it left view. GEIPAN assesses a moderate amount of reliable, objectively supported information: 2 witnesses but 1 account, with no photograph or video. This assessment concerns the quantity of such information collected for an account. It investigated a helium-filled Mylar balloon and a drone; see the report. More arguments favour the balloon: rotation, high altitude, reflected sunlight and final movement with the wind that carried it out of sight. GEIPAN classifies the case B: probable observation of a windborne Mylar balloon.
