SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2021-09-26T12:36:00-CME-001 (version 1)
Source Location: S28W19
Active Region Number: 12871
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
Note: The CME appears wider in STEREO A images than in SOHO images. The source of this CME is an eruption associated with a C1.6 class flare that peaked at 11:24Z from AR12871. The eruption started around 11:20Z and exhibited potential deflection within the field of view as well as opening field lines in the SW of SDO/AIA 171.
