Gushing Green

The brilliant Northern Lights fill the sky above a radar dish in Svalbard, Norway, on a crisp December night (temperatures dipped to minus 4 degrees F,or minus 20 degrees C) in 2006 when Cyril Simon Wedlund captured this image. Scientists were in the process of taking measurements using the European Incoherent Scatter Svalbard Radar to learn more about the aurora and the ionosphere. This aurora was very dynamic and one of the most beautiful that we watched during this period of waning solar activity,writes Wedlund.
