Last night Earth experienced a geomagnetic storm and aurora were visible in the Northern U.S. states. These images of aurora were captured on March 17, 2015, around 5:30 a.m. EDT in Donnelly Creek, Alaska by Sebastian Saarloos. These aurora might have been caused by the fast solar wind streaming from two solar coronal holes. Image Courtesy of Sebastian Saarloos.
