Sighting in Os-Marsillon, October 17, 2011

At around 8:40 pm on an October evening, the witness was standing at their front door when they noticed three white points of light in the sky. Each looked about five times larger than a star. The group, arranged in a triangle, crossed the sky from south toward west. The three lights seemed to drift slightly apart, then come back together before vanishing at the western horizon. They moved at about the speed of a shooting star, and the sighting lasted less than 5 seconds.

GEIPAN considered the case consistent, with low to moderate strangeness. Two explanations were considered. One was Chinese lanterns, but the sighting was very short, unless the witness misjudged its length. The other was an atmospheric re-entry (a fireball or a meteorite fall), which fits the duration better, although several objects at once is rare. No further investigation was carried out to decide between the two hypotheses, so the case was provisionally classified C, for insufficient data.
