G3 (Strong) Geomagnetic Storm Watch remains in effect for 31 Mar

G3 (Strong) Geomagnetic Storm Watch remains in effect for 31 Mar
published: Friday, April 01, 2022 14:40 UTC

A G3 (Strong) geomagnetic storm watch remains in effect for the remainder of 31 March. Additionally, the G2 (Moderate) watch continues in effect for 1 April as Coronal Mass Ejection (CME) progression continues. The CME arrived at the NOAA DSCOVR spacecraft, about 1 million miles from Earth, on 30 March 9:40 pm EDT (31/0140 UTC); detected as an interplanetary shock. CME arrival at Earth was noted in the planetary magnetometer network as a sudden impulse 30 minutes later at 10:10 pm EDT (31/0210 UTC). G1 (Minor) storm levels were reached shortly afterwards. Enhanced solar wind conditions continue to show the potential for elevated geomagnetic responses to the G2-G3 levels. Any prolonged or pronounced southward shift in the interplanetary magnetic field (IMF) could quickly escalate geomagnetic reactions to storm levels.
