Source NASA: A strong-to-severe (Kp=8) geomagnetic storm is in progress following the impact of a coronal mass ejection impact of a coronal mass ejection (CME) at approximately 8:15a.m. EDT (12:15 UT) on Sept. 26. The Goddard Space Weather Lab reported a strong compression of Earth’s magnetosphere. Simulations indicate that solar wind plasma has penetrated close to geosynchronous orbit starting at 9am. Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields. High-latitude sky watchers should be alert for auroras after nightfall.
