During this time-lapse taken from the VLT complex at Paranal observatory, I caught an small sequence of a rare blurred object (0:14-0:18). The object is probably related to the launch of the FengYun-2F satellite from China (2012-01-13 at 00:56 UT), because is consistent with the moment when this object appeared in the sky (01:39 UT). The object turned fainter and vanished after some minutes.
P.S. Thanks to Douglas Pierce-Price for your help in identify this object!
