G2 (Moderate) Geomagnetic Storm Watch for 31 March, 2022

G2 Watch for 31 March, 2022
G2 (Moderate) Geomagnetic Storm Watch for 31 March, 2022
published: Tuesday, March 29, 2022 19:19 UTC

A G2 (Moderate) geomagnetic storm watch is in effect for 31 March, 2022. A Coronal Mass Ejection (CME) erupted on 28 March associated with an M4 flare at 7:29 am EDT (1129 UTC). Initial analyses and model guidance suggests a portion of the CME will arrive during the late evening of 30 March into early morning of 31 March (EDT). Forecast confidence of an Earth-directed component is moderate, while there is less confidence in timing and intensity. When the CME approaches Earth, NOAA’s DSCOVR satellite will detect the real-time solar wind changes and SWPC forecasters will issue any appropriate warnings. Impacts to technology from a G2 storm are generally small, but it can drive the aurora equatorward of its polar home. Aurora may be visible over the northern portions of the northern tier states if the conditions are favorable. For additional information, visit our phenomena pages at space weather, geomagnetic storms, CMEs, and aurora and viewing tips, and CMEs.
