Breaking: Geomagnetic Storm As Coronal Mass Strikes Earth

CME IMPACT, SEVERE GEOMAGNETIC STORM: Arriving earlier than expected, a CME hit Earth's magnetic field on March 17th at approximately 04:30 UT. At first, the impact sparked a relatively mild G1-class  geomagnetic storm. Since then, however, the storm has intensified to G4-class , ranking it as the strongest geomagnetic storm of the current solar cycle. This storm is underway now. 

Before sunrise, bright auroras were sighted over several northern-tier US states including Minnesota,Wisconsin, Montana, the Dakotas and Washington. Marketa Murray sends this picture from Dalton Highway in Alaska. 

Auroras may appear as far south as Alabama.
