A CME hit Earth’s magnetic field on March 17th at approximately 04:30 UT, arriving earlier than expected.
The impact sparked a relatively mild G1-class (Kp=5) geomagnetic storm which has now intensified to G4-class (Kp=8), representing the strongest geomagnetic storm of the current solar cycle.
This storm is underway now and could continue for many hours to come as Earth passes through the turbulent wake of the CME.
Now look at the amazing and bright auroras pictures captured and sighted all over the world from over several northern-tier US states including Iowa, Minnesota, Wisconsin, Montana, the Dakotas and Washington, Canada, Europe and New Zealand.
