Saint-Martin-de-Crau 1991, light show attributed to laser projector

Summary

Around 10:30 PM on an August night in 1991, a witness watched a series of white dots moving chaotically across the sky over Saint-Martin-de-Crau. Suddenly the dots arranged themselves into geometric shapes, forming a kind of luminous ballet for about five minutes before merging into a single point that vanished, leaving a brief trail. Though the scene was puzzling, the witness herself mentioned a nearby nightclub equipped with laser projectors, which is the most likely explanation for the phenomenon.
