“A Severe (G4) Geomagnetic Storm is LIKELY - possibly as early as later today and continuing through the weekend; exact timing remains somewhat uncertain. At least seven
earth-directed Coronal Mass Ejections (CMEs) are in transit

Only three Severe (G4) geomagnetic storms have occurred so far this solar cycle (since 2019); the last was a brief occurrence on March 23. This is SWPC's first G4 Watch since 2005”
