An account in Essonne, France

On August 29, 2008 at 10:45 PM, a witness looks through his closed window and is intrigued by the presence of a white light similar to a star but much brighter, to the northwest. The observation lasts about 6 seconds, during which the witness sees the UAP move, stop, then disappear. No other testimony was collected. This testimony represents little strangeness. The various descriptions also refer to a star. The little strangeness could come from this description ("fixed then slight acceleration then fixed again") but it is not consistent with another ("The phenomenon moved slowly to the north then stopped and disappeared"). Moreover, the duration of the observation is short (6 seconds). It is also noted that this testimony was made nearly 18 months after the observation. Overall, GEIPAN considers that it does not have enough reliable information to conclude on a picture where nothing rules out a star (the proximity of a moving cloud can give the impression of movement before the progressive extinction interpreted as a rapid escape into the distance) or a Thai lantern. GEIPAN classifies this case as C: lack of information.
