Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-02T14:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-09-02T14:09:00-CME-001 (version 1)
Source Location: N30E40
Active Region Number: 14207
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME faintly visible to the NNE in STEREO A COR2 and the N in SOHO LASCO C2/C3. Obscured by the pylon in GOES CCOR-1. The potential source may be AR 14207 (N30E40), with an eruption characterized by rising loops, best seen in SDO AIA 193/335 starting at 2025-09-02T12:20Z. The eruption is also visible on the limb in STEREO A EUV imagery. Moving field lines can be seen beyond the NE limb in SDO imagery, but the CME was determined to most likely not be farsided.
