Solar Storms at CME Halo
Reported by SOHO LASCO today.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-09-03T22:36Z. Linear speed: 1020 km/s. Half-angle: 25°. Full halo CME — potential global geomagnetic impact. CME visible to the SE in SOHO LASCO C2, C3, GOES CCOR-1, and STEREO A COR2 imagery. The source of this CME is a filament eruption visible to the SE in GOES SUVI 304 with associated moving/opening fiel
How we know
One source: SOHO LASCO. Not yet confirmed by a second, independent source.
Our own score for this event is 35 out of 100, at 50 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v4. Rows carrying other versions were judged by different rules and are not directly comparable.
