Note: This CME is visible to the southwest in SOHO LASCOC2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source may be related to an eruption from Active Region 14217 (S16W51) starting around 2025-09-24T05:50Z as seen in GOES SUVI 131, 171, 195, 304 imagery. However, there is faint field line movement visible over the southwest limb in GOES SUVI 284 imagery around this time which may also indicate a far-sided source.
