Severe G4-class geomagnetic storm hit Earth on March 24

Space.com — March 25, 2024, 03:00 PM UTC

Summary: On March 22, 2024, a powerful X-class solar flare led to a coronal mass ejection hitting Earth on March 24, causing a severe G4-class geomagnetic storm, the strongest since 2017. NOAA ranks geomagnetic storms from G1 to G5, with G4-class storms potentially visible as far south as Alabama. Despite expectations, the storm's impact on auroras was limited due to a strong northward Bz shift.
