Solar Storms at CME Halo
Right now
The most recent data we hold from SOHO LASCO arrived 10 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 101 days ago.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-06-03T01:53Z. Linear speed: 1390 km/s. Half-angle: 32°. Full halo CME — potential global geomagnetic impact. CME first seen to the E in STEREO A COR2 starting at 2026-06-03T01:53Z. It is also faintly seen as a halo to the NW in SOHO LASCO C2/C3 but is partially obscured by the pylon. It is also seen as a hal
How we know
One source: SOHO LASCO. Not yet confirmed by a second, independent source.
Our own score for this event is 15 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.
