CME Halo — 1262 km/s
Coronal Mass Ejection detected at 2026-05-23T19:53Z. Linear speed: 1262 km/s. Half-angle: 32°. Full halo CME — potential global geomagnetic impact. Fast CME with a brighter, narrower bulk partially obscured by the pylon in GOES CCOR-1 and a fainter halo shock seen to the N in COR2A and to the NE in CCOR-1 (and initially covered by the scheduled d
