Source Location: S13W45
Active Region Number: 14224

Note Keyword:

Source Signature Keyword:

FLR: Flare

OFL: Moving/Opening field lines

J: Jet

Note: Jet CME seen to the SW in SOHO LASCO C2/C3 and GOES CCOR-1. Seen extremely faintly in STEREO A COR2. Source is likely narrow opening field lines and an M1.0 flare seen from AR 14224 (S13W45) seen in GOES SUVI 195 starting around 2025-09-24T08:44Z. A small amount of ejecta can also be seen in STEREO A EUVI 304 at 2025-09-24T09:15Z.
