January 24, 2013
This picture of XMM-Newton was taken at 04:00 UTC using a front-illuminated CCD camera through a 40 cm f/4 telescope. The exposure time was 30 seconds and the field of view is 20' x 20'. At the time, the satellite was near its perigee at a distance of 8440km. On the image it leaves a long trail, travelling from the right to the left side at an angular speed of 2.4 degrees/minute.
