NOAA's Space Weather Prediction Center issued a watch for a strong geomagnetic storm expected to reach Earth Wednesday March 30, 2022

A G3 (Strong) geomagnetic storm watch is now in effect for 31 March, 2022. A second, faster Coronal Mass Ejection (CME) erupted later on 28 March associated with an M1 flare at 3:23 pm EDT (1923 UTC). Analyses indicated the CME speed as approximately 841 km/s, and model guidance suggests this CME will overtake the day’s earlier CME and arrive during the early evening of 30 March into early morning of 31 March (EDT). Forecast confidence of an Earth-directed component is good, with moderate confidence of timing and intensity. Additionally, a G1 (Minor) watch is in effect for 30 March, 2022, for likely effects of initial CME shock arrival and a G2 (Moderate) watch is in effect for 1 April, 2022, in anticipation of continuing, but weakening, CME influences.
