Geomagnetic Storms Space Weather Scale, according to the NOAA Space Weather Prediction Center. The source of the storming is an Earth-directed Coronal Mass Ejection
The geomagnetic field is expected to be unsettled with isolated active periods for day one (08 April) due to coronal hole effects. Quiet to unsettled conditions are expected for day two (09 April).
Systems that can be affected include electric power systems, spacecraft operations, high-frequency communications, GPS, and other navigation systems.
