Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-21T10:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2025-01-21T10:53:00-CME-001 (version 3)
Source Location: S18E23
Active Region Number: 13967
Note Keyword:
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
DFLR: Double ribbon flare
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright CME and faint shock to the SE in STEREO COR2A, not yet observed in SOHO LASCO C2/C3 due to a downlink gap except for a very few late SOHO C3 frames. The source is an M3.3 class flare from AR 3967 peaking at 2025-01-21T10:39Z. Starting around 2025-01-21T09:42Z, a wide area of the disk East and South of AR 13967 brightens up in SDO AIA 304/GOES SUVI 304 with observed filament ejecta fanning out to the SE. Field line movement and extensive dimming, with an EUV wave, over this area also observed in SDO AIA 171/193/211. Partially overlaps with far-sided CME: 2025-01-21T09:12Z.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
