Coronal mass ejection — 2026-10-05 21:12 UTC
This CME is visible to the northwest in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is likely related to a far-sided filament eruption which begins to lift-off around 2026-10-05T19:00Z as seen in SDO AIA 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery.
