It's hard to even dream landscapes like the one shown above; stunning chartreuse auroras draping the northern horizon and reflecting off of a subarctic lake, rafts of drifting ice and the Big Dipper and other circumpolar constellations accenting the surreal scene. This photo was taken with a fisheye lens at Jokulsarlon, Iceland on September 19, 2012 during an auroral substorm -- one of the most active in years. The constantly changing curtain patterns consist of parallel rays that are all oriented with the local direction of geomagnetic field lines. On the smaller photo, I luckily captured a brilliant meteor (brighter than Venus) along with the northern lights. Fortunately, the weather cooperated throughout this magnificent display.
