Note Keyword:
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint outflow CME to the SW in SOHO LASCO C2, C3, and STEREO A COR2 imagery. Not clearly visible in GOES CCOR-1. No clear source, but likely associated with restructuring following large CME eruptions to the W/SW starting at 2025-09-06T13:36Z through 16:48Z.
