Aurora Australis looking south from the Port Hills near Christchurch, New Zealand. That is Lake Ellesmere in the foreground on the right. This was probably the most prominent banding I caught during the evening. I've got a timelapse video available on YouTube: youtu.be/LnXlVeTfetw Note that this version is pretty much straight out of camera, with default Adobe Lightroom 4 processing.
Update 21 July: I have also received quite a few requests for a 1080p version for desktop backgrounds, you can find it here -> flic.kr/p/cAPMEy <- This linked version has had some post-processing, has been cropped to suit 1920x1080 display, and has been release under a Creative Commons license. Thanks for the interest!
