UPDATE! An X8.1 (Strong) flare from Region 4366

UPDATE! An X8.1 (Strong) flare from Region 4366
published: Monday, February 02, 2026 12:27 UTC

Region 4366 produced another strong X8.1 (R3) flare at 6:57 pm ET. Modeling of the associated coronal mass ejection(s) indicates that a bulk of the material will pass by Earth to the north and east late on the 05 Feb UTC-day delivering possible glancing influences. Region 4366 continues to produce M and X-class flares as of early Monday morning. SWPC forecasters expect more exciting activity from this region in the coming days!
