Note: This CME is visible to the southwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. It is currently not observed in STEREO A COR2 imagery due to a data gap starting at 2025-09-24T14:53Z. The source is likely related to an eruption from Active Region 14217 (S16W57) starting around 2025-09-24T14:00Z as seen in GOES SUVI 131, 171, 195, 304 imagery.
