Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-04T15:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-04T15:12:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: Faint CME seen to the SSW in SOHO LASCO C2/C3, and directly S in STEREO COR2A. The source is likely dimming in the far southern area of the disk, centered around S60W20, observed in SDO AIA 193 around 2025-04-04T15:00Z. This may, unlikely, be related to a C4.4 flare from AR 14502 (S23W29) which peaked at 2025-04-04T14:46Z, it is difficult to discern if this flare erupted in this deflected direction, the dimming at S60W20 is an sympathetic eruption, or if the dimming at S60W20 is entirely separate. Thus it is not currently attributed as a source, and noted for completion of the analysis.
