The Sun remained active last week, unleashing on April 15 a powerful X14-class solar flare near sunspot 9415 . The resulting interplanetary shock wave swept past Earth and triggered a strong (G3-category) geomagnetic storm, resulting in a spectacular aurora display on April 17/18 as captured above by Dominic Cantin of St. Michel, Quebec, Canada.
