Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-20T10:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-02-20T10:36:00-CME-001 (version 2)
Source Location: S10E60
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: Wide CME seen to the east in SOHO LASCO C2 and STEREO A COR2 composed of a brighter bulk to the south and possibly a separate portion just to the north. Likely associated with large scale dimming taking place near S10E60 seen best in GOES SUVI 195 and SDO AIA 193 starting at 2025-02-20T09:28Z. Triangulation of the leading edge measures a bit closer to the Earth-Sun line than anticipated, and this may be due to a simultaneous eruption occurring near center disk around 2025-02-20T11:00Z.
