ATHIS-MONS (91) 29.08.2008

On 29 August 2008 at 22:45, a witness in Athis-Mons (91) looked through a closed window and saw a white light to the northwest, star-like but much brighter. Over about 6 seconds, he saw it move, stop and disappear. No other account was collected. GEIPAN judges the unusualness low; the descriptions repeatedly compare the light to a star. One sequence is described as stationary, then slightly accelerating, then stationary again, whereas another says it moved slowly north, stopped and disappeared. GEIPAN considers these accounts of movement inconsistent. The sighting was brief and reported nearly 18 months later. There is insufficient reliable information to conclude. A star remains possible: a nearby moving cloud could create apparent motion, with subsequent gradual fading interpreted as rapid movement away. A sky lantern also remains possible. GEIPAN classifies the case as C: lack of information.
