This video of UARS (Upper Atmosphere Research Satellite) has been taken from Northern France (Dunkerque) on September 15th 2011 between 04:42:14 and 04:44:02 UTC. Distance to observer: 316 km. Altitude of the satellite: 252 km. Angular speed at culmination: 1.36/s. The speed of the sequence is accelerated two times with regard to real time (20 fps vs 10 fps). The satellite is tumbling, perhaps because of a collision with satellite debris a few years ago.

The satellite is out of control and its atmospheric reentry is currently scheduled for Friday Sept 23th, plus or minus one day.

Instrument: Celestron EdgeHD 14 Schmidt-Cassegrain telescope (at a focal length of 8500mm) on automatic tracking system, as described on this page. Camera: Lumenera Skynyx L2-2.
