Activity ID: 2026-01-05T08:48:00-CME-001 (version 3)
Source Location: S17E43
Active Region Number: 14334

Note Keyword:

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

F: Flux Rope

Note: Faint CME seen to the southeast in SOHO LASCO, STEREO A COR2A and GOES CCOR-1 possibly associated with a two-part eruption in AR 4334 (S17E43) seen best in SDO AIA 171 around 2026-01-05T08:20Z; while most of the plasma material is directed southward, a portion of the plasma lags behind and is directed to the southeast. May instead be associated with a destabilizing magnetic loop with bright post eruptive arcades high above the AR 4334 (S17E43), but the ejecta does not leave the GOES and SDO EUV field of views until after 09:00Z, suggesting that any such CME associated with the later eruption in AR 4334 is seen after 09:00Z in coronagraph imagery.
