CME Halo — 1580 km/s
Coronal Mass Ejection detected at 2026-07-30T16:53Z. Linear speed: 1580 km/s. Half-angle: 37°. Full halo CME — potential global geomagnetic impact. CME observed as a NE halo in STEREO A COR2, and a NW halo in GOES CCOR-1 partially blocked by the pylon. SOHO LASCO C2/C3 not available in real-time due to a downlink gap, but observed as a NW halo he
