Solar Storms at CME Halo
Right now
The most recent data we hold from SOHO LASCO arrived 4 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 99 days ago.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-06-06T14:11Z. Linear speed: 1692 km/s. Half-angle: 45°. Full halo CME — potential global geomagnetic impact. This CME is visible as a southeast partial halo in SOHO LASCO C2/C3 and GOES CCOR-1 imagery, and is seen to the east in STEREO A COR2 imagery. The source is an eruption and M1.8 flare from Active Regi
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.
