Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-18T11:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-18T11:00:00-CME-001 (version 1)
Source Location: N24W87
Active Region Number: 14246
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
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
Morphology Keyword:
F: Flux Rope
Note: Minor CME to the NNW seen in SOHO LASCO C2 and later C3, in GOES CCOR-1 and STEREO A COR2 coronagraphs. Its source could be the M1.5 flare from AR 4246 (N24W87) starting at 2025-10-18T10:37Z or a very minor filament seen erupting in GOES SUVI 304 after 2025-10-18T10Z.
