Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-27T00:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-02-27T00:12:00-CME-001 (version 1)
Source Location: S16W86
Active Region Number: 13996
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the west/southwest in SOHO LASCO C2/C3 imagery. This event is not observable in STEREO A COR2 due to a data gap. The source is likely related to a C3.5 flare and eruption from Active Region 13996 (S16W86) starting around 2025-02-26T22:50Z as seen in SDO AIA 131 imagery. Faint field line movement is visible over the southwest limb at this time in SDO AIA 171 and 193 imagery as well.
