IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field at approximately 12:15 UT on Sept. 26th. The impact caused significant ground currents in Norway. Also, the Goddard Space Weather Lab reports a "strong compression of Earth's magnetosphere. Simulations indicate that solar wind plasma [has penetrated] close to geosynchronous orbit starting at 13:00UT." Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields. Stay tuned for updates.
