Solar Storms at CME Halo
Right now
The most recent data we hold from SOHO LASCO arrived 5 hours ago, and this point is in it.
Reported by SOHO LASCO 2 days ago.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-09-05T15:36Z. Linear speed: 1111 km/s. Half-angle: 42°. Full halo CME — potential global geomagnetic impact. Bright CME observed to the SW in SOHO LASCO C2/C3 and GOES CCOR-1, and as a full halo in STEREO A COR2. The source is associated with an M1.0 flare from AR 14520 peaking at 2026-09-05T15:18Z, observed
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 49 % 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.
