An unusual arc of stationary aurora, arcing across the sky from west to east like a searchlight, but with little motion. Well seen across western Canada that night, August 5-6, 2005. Photographed here from Saskatchewan Summer Star Party, with Canon 20Da camera and 16mm lens at f/2.8 and ISO 400 for 3 minutes, tracked. Contrast boosted but aurora colors left untouched. Arc was primarily pink.
