CME Halo — 914 km/s
Coronal Mass Ejection detected at 2026-04-15T11:53Z. Linear speed: 914 km/s. Half-angle: 44°. Full halo CME — potential global geomagnetic impact. Fast CME to the W/NW in STEREO A COR2 imagery appearing more as a partial halo to the W/NW in GOES CCOR-1 imagery. There is currently a data gap for this event in SOHO LASCO C2/C3 imagery. The source
