Note: This CME is visible to the southwest in STEREO A COR2 and SOHO LASCO C3 imagery. It is also visible in SOHO LASCO C2 following a data gap ending at 2025-02-27T07:48Z. The source is likely related to an eruption from Active Region 13996 (S16W89) starting around 2025-02-27T05:00Z as seen in SDO AIA 131 and 304 imagery. Faint field line movement is visible over the southwest limb around this time in SDO AIA 171 and 193 imagery as well.
