Solar Storms at CME Halo
Right now
The most recent data we hold from SOHO LASCO arrived 21 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Reported by SOHO LASCO 110 days ago.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-05-25T22:12Z. Linear speed: 1980 km/s. Half-angle: 31°. Full halo CME — potential global geomagnetic impact. Fast, halo CME first seen to the NW by SOHO LASCO C2 beginning at 2026-05-25T22:12Z, as well as by SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1 in later frames. The source of this event is likely a fa
How we know
One source: SOHO LASCO. Not yet confirmed by a second, independent source.
Our own score for this event is 22 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 v1. Rows carrying other versions were judged by different rules and are not directly comparable.
