Activity ID: 2025-03-21T16:36:00-CME-001 (version 1)
Source Location: S17W33
Active Region Number: 14028
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: CME visible to the SW in SOHO LASCO C2 and C3 imagery. No STEREO A COR2 imagery for this event due to a data gap. The source of this CME may be the M1.2 flare from AR14028 (S17W33) as seen in SDO/AIA 131 and 193. There is clear dimming and moving/opening field lines visible to the SW of the eruption suggesting deflection. This may be due to a coronal hole due north of the source location.
