Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-04T03:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-12-04T03:24:00-CME-001 (version 2)
Source Location: N10E58
Active Region Number: 14300
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare

Note: Faint CME observed to the E in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is an M6.0 class flare from AR 14300 (N10E58) which peaked at 2025-12-04T02:50Z best observed in GOES SUVI 131. Additionally observed as wide field line movement/EUV wave in GOES SUVI 171/195/284, with some dimming around the region in GOES SUVI 195.
