Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-04T18:30Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
SOHO: LASCO/C3
Activity ID: 2025-09-04T18:30:00-CME-001 (version 2)
Source Location: S40W40
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
F: Flux Rope
Note: CME to the SW seen in GOES CCOR-1 and SOHO LASCO C3 and fully covered by a data gap in STEREO A COR2. Its source is a minor eruption at around S40W40 (or 50) seen in AIA 193 as ejecta and a following dimming, with post-eruptive dimming best seen starting around 2025-09-08T18:48Z.
