Note: Very narrow CME first seen to the SW in SOHO LASCO C2 starting around 2026-09-13T07:48Z. It is first seen part way into the FOV of SOHO LASCO C2 and is also seen in SOHO LASCO C3 and GOES CCOR-1 but not in STEREO A COR2. The source may be related to minor field line movement beyond the SW limb best seen in SDO AIA 171 beginning around 2026-09-13T06:00Z.
