COLLEVILLE (76) 12.10.2024

On the evening of 12 October 2024, a Colleville (76) resident, T1, his wife T2 and their son T3 saw regular blue flashes at the horizon above neighbours' roofs from the driveway in front of their home. The flashes remained in the same place at a constant angle for about 3 minutes. GEIPAN finds low strangeness and a good amount of reliable, objectively supported information despite only 1 account, with 3 observers and a video. It considers a sky-tracer probable: an outdoor single- or multiple-beam projector with a 180° sweeping mechanism. The evidential assessment concerns the quantity of such information collected for an account. Straight-line flashes appearing regularly in alternation every second strongly match this explanation, especially on a Saturday evening with overcast sky. The investigation could not identify the exact source; see the report. GEIPAN classifies the case B: probable observation of a sky-tracer.
