Solar Storms at CME Halo (Earth-directed)
Right now
The most recent data we hold from SOHO LASCO arrived 29 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 119 days ago.
What the source measured
SOHO LASCO reported: Coronal Mass Ejection detected at 2026-05-10T13:48Z. Linear speed: 1540 km/s. Half-angle: 54°. Full halo CME — potential global geomagnetic impact. ENLIL model indicates Earth-directed component. This CME is visible to the northeast as a partial halo seen in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is an M5.7 flare and eruption from Active Region 14436 (centered nea
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 50 % 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.

| Note | This CME is visible to the northeast as a partial halo seen in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is an M5.7 flare and eruption from Active Region 14436 (centered near N21E65) starting around 2026-05-10T13:30Z as seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/19 |
