Solar Storms at CME Halo (Earth-directed)
Reported by SOHO LASCO today.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-09-02T19:36Z. Linear speed: 1323 km/s. Half-angle: 39°. Full halo CME — potential global geomagnetic impact. ENLIL model indicates Earth-directed component. Bright CME visible to the NE in SOHO LASCO C2, C3 and GOES CCOR-1 imagery. This CME is not visible in STEREO A COR2 imagery due to a data gap. The source of this CME is an M3.0 flare from an unnumbere
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.
