An account in Essonne, France
On October 20, 2011 at around 9:10 PM, an amateur astronomer observes the slow West-East movement of a luminous point. Of low strangeness and good consistency, this observation case relates a particularly bright luminous point, moving from West to East, rising toward the celestial vault and disappearing in a few seconds. This corresponds exactly to the appearance of the ISS disappearing into the Earth's shadow. A slight discrepancy is noted between the disappearance time (9:03 PM) provided by the simulator and the observation time (9:10 PM), and a maximum elevation lower than the witness's reading (50° versus 60/70°): ISS orbit bulletins change notably from one day to the next during that period, probably due to maneuvers; it is very difficult to have a very precise orbit bulletin in these situations. This case is classified B: probable observation of the International Space Station ISS.
A witness observes, on July 3, 2010, starting at 11:50 PM, the movements of a white luminous point in the sky that intrigues them. No particular noise is heard during the filmed observation.…
