Coronal mass ejection — 2026-10-26 01:26 UTC
This CME is visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. This CME is not visible in STEREO A COR2 in real time due to a data gap. The source may be related to an opening of field lines visible over the western limb in SDO AIA 171 imagery starting around 2026-10-25T23:55Z, likely associated with a small eruption from Active Region 14560 (N14W75).
