won an international competition for landscape astrophotography. The featured winning image was taken in 2011 over JÆkulsÀrlÑn, the largest glacial lake in Iceland. The photographer combined six exposures to capture not only two green auroral rings, but their reflections off the serene lake. Visible in the distant background sky is the band of our Milky Way Galaxy and the Andromeda galaxy. A powerful coronal mass ejection from the Sun caused auroras to be seen as far south as Wisconsin, USA. Solar activity over the past week has resulted in auroras just over the past few days.
