SEVERE GEOMAGNETIC STORM:  A coronal mass ejection (CME) hit Earth's magnetic field during the early hours of March 17th, triggering a magnetic disturbance that has escalated into the strongest geomagnetic storm of the current solar cycle (Kp=8).  During the hours before sunrise on St. Patrick's Day, bright green skies appeared over multiple US states including Wisconsin, Washington, Minnesota, and the Dakotas.
