Just after 1:00 a.m. and after we had gone to bed with heavy snow falling at our accommodation near Lake Myvatn, Iceland, the sky cleared a bit and a very faint green glow appeared on the horizon. We quickly threw on warm clothes and headed outside into the cold wind just in time for this aurora to become really active. It was only visible for about an hour, but we watched the green wisp glimmer and billow until the very last second it faded from our view and danced away. Auroras form when energetic particles emanating from the Sun are guided along the Earth’s magnetic field lines toward the magnetic poles. If these particles come in contact with oxygen atoms, green light is emitted. Photo taken on January 4, 2013.
