The Canadian Space Agency has set up a website that allows the live viewing of the northern lights from Yellowknife, in the Northwest Territories. You can watch live during the appropriate hours, as well as watch the previous night’s video in time lapse and selected videos from especially active nights.
The videos are pretty small and not super high resolution. The ‘AuroraMAX’ site would probably benefit from the addition of some large still photos. The sun’s 11-year cycle of activity is expected to peak in 2013, and the site has a mandate to carry on until then. The site doesn’t say what kind of equipment is being used, but it seems to be a fisheye lens on either a video camera or dSLR.
