Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-04T13:09Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-09-04T13:09:00-CME-001 (version 2)
Source Location: N28E18
Active Region Number: 14207
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: Faint hight N latitude CME with the likely source a long, very narrow eruption/ejecta in AR 4207 (N28E08) starting at 2025-09-04T10:50Z and going on potentially through 2025-09-04T12Z, and seen in SDO AIA 304, STEREO A EUV 304 and GOES SUVI 304. There is a C2.8 flare from AR 4207 (N30E18) peaking at 2025-09-04T10:55Z likely associated with this CME.
