Wednesday morning from my campsite at the Nebraska Star Party by Valentine, NE. After looking at the arc of clouds in the north for 30 minutes I realized they were not clouds! While your eyes could not see the color the first photo I took confirmed my suspicion that this was an auroral glow. An hour later the glow had diminished but occasionally you were seeing more structure in display. Picture taken about 00:45 using a Canon 40D with 12mm lens, 30s at f4, ISO 1600, with some adjustments in Lightroom and Photoshop.
