Unexpected mostly clear night with bright NLC in the NNE (stretching from NNW to just E of NE). Substantial low cloud on the horizon but I managed to grab this shot:


Jul 10, 0144 UT. Canon 40D, 17mm, 2.5 sec at f/5.6, ISO 400.

The "bright" cloud stretching across the top of the frame is tropospheric cirrus cloud, probably a smeared contrail.
