Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-11T10:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-11-11T10:23:00-CME-001 (version 1)
Source Location: N27W27
Active Region Number: 14274
Note Keyword:
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
SEP: Solar Energetic Particle event
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Large halo CME first seen to the NE by STEREO A COR2 beginning at 2025-11-11T10:23Z, as well as to the NW by SOHO LASCO C2/C3 and GOES CCOR-1 in later frames. The source of this event is an X5.1 flare from Active Region 14274 (N27W27) which peaked at 2025-11-11T10:04Z as seen in GOES SUVI 131. Wide opening field lines and a large EUV wave and instance of dimming is visible in GOES SUVI 195 and 284 and STEREO A EUVI 195, along with post eruptive arcades visible in GOES SUVI 131 and 195.
