UPDATED: G3 (Strong) Geomagnetic Storming Observed 22 Mar
published: Sunday, March 22, 2026 16:42 UTC

UPDATED: G3 (Strong) geomagnetic storming was observed during the 0900-1200 UTC synoptic period on 22 Mar as what is likely high speed stream onset began coupled with waning CME influences. G1-G2 storming levels are being observed and another isolated period of G3 level is expected until the end of the UTC-day.
