CME faintly visible to the southwest in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is not clear, but may be some faint field line movement seen to the west in STEREO A COR2 EUV 195 imagery around 2026-11-13T08:00Z. Dimming is also seen to the south of the large coronal hole seen in STEREO A EUV 195 imagery as well. Moving/opening field lines are visible beyond the west limb in SDO AIA 171 in ISWA starting at 2026-11-13T08:27Z.
