Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-28T15:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-28T15:24:00-CME-001 (version 1)
Note Keyword:
DPL: CME exhibits dimpled front
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
OS: Other and Shock Candidate
Note: CME observed to the E in SOHO LASCO C2/C3 and GOES CCOR-1, not observed in available STEREO A COR2 imagery likely due to CME direction behind the COR2 occulting disk. The source is not directly observed, but clearly seen as wide field line opening and an EUV wave far over the east limb in GOES SUVI 171/195/284 starting around 2025-10-28T14:49Z.
