CME Halo (Earth-directed) — 1744 km/s
Coronal Mass Ejection detected at 2026-04-24T08:24Z. Linear speed: 1744 km/s. Half-angle: 47°. Full halo CME — potential global geomagnetic impact. ENLIL model indicates Earth-directed component. Bright wide CME with a brighter bulk and a fainter, more halo-like shock seen to the NW in SOHO LASCO and STEREO A CCOR-1 and to the N (slightly to the NNW) in STEREO A COR2. Its source is the X2.5 fl
