Shown above are the Northern Lights and the stunning Hraunfossar (lava falls), in western Iceland. These falls are formed from a stream flowing underneath the Hallmundarhraun lava field -- the stream empties into the Hvítá River.
As the daylight period lengthens in spring and summer the aurora season comes to an end. This pale green aurora resulted from a moderate geomagnetic storm (Kp6 classification) that occurred in late March. The bright star on the right is Vega, in the constellation of Lyra. The Milky Way is hidden behind the auroral curtain, but the Andromeda Galaxy, the closest major galaxy to the Milky Way, is visible at the lower left. Photo taken on March 27, 2017.
