Sighting in Coulon, July 3, 2025

During the night, the witness was at home with the window open and noticed seven or eight small green lights arranged in a circle. The circle rotated on itself, and the lights then moved in jerks. They later gathered into a teardrop shape and passed over the house, going back and forth and returning at times to a circular arrangement. The observation lasted about five minutes, until the witness chose to stop watching. Afterwards, they heard two dull thuds followed by dogs barking. The witness was alone and took no photo or video, and the case was rated as having medium consistency.

The investigation looked at event-lighting projectors known as sky-tracers, whose beams point at the sky and move in regular, repeated patterns, often circles or back-and-forth sweeps, and can also come together and separate. This matches the description. A low cloud layer covered the sky, which allows such beams to produce spots of light on the cloud base. Green is not the most common colour, but it is possible with coloured filters. Niort lies about 9 km away, and these projectors can light up to 20 km, so their use was technically possible. However, nothing indicated that local entertainment or nightclubs used sky-tracers that evening. A private outdoor party with rented projectors could not be ruled out. The two dull thuds might have been firecrackers from such an event, though no direct link to the sighting could be established. GEIPAN classified the case as B: probably light animations produced by sky-tracers.
