Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-26T14:23Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-26T14:23:00-CME-001 (version 2)
Source Location: N12E70
Active Region Number: 14100
Note Keyword:
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
FIL: Filament eruption
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: A relatively bright CME seen to the east in all three coronagraphs. Its source is the M1.4 flare from AR 14100 (N12E70) and the associated ejecta seen in SDO AIA/GOES SUVI/EUVI A 304 around 2025-05-26T13:21Z (ejecta directed northward). Coronal signatures include intense dimming, brightening, post-eruptive arcades and even a wide EUV wave seen almost reaching the central meridian in SDO AIA.
