Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-02-24T20:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-02-24T20:36:00-CME-001 (version 4)
Source Location: N29W24
Active Region Number: 13229
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
PRM: Prominence material (filamentary structures)
SEP: Solar Energetic Particle event
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Partial halo CME seen mostly to the NW in SOHO LASCO and STEREO A COR2A coronagraphs. The CME is associated with an M3.7-class flare and subsequent eruption from AR3229. The flare induces a large nearby filament channel to break and lift off seen best in SDO/GOES 304, but also in SDO 193 and GOES-16 195. The flare and CME are also associated with a small enhancement in 10 MeV protons observed at GOES.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME |

This is a very preliminary measurement with only 4 frames in STEREO A using SWPC_Cat. The CME leading edge is better visible in the last few frames so the shock is not accounted here for. The particles are getting elevated in all instruments, SOHO, STA and GOES. There is a big EUV wave seen towards Earth in SDO images (171/193). The CME needs to be remeasured when SOHO C3 images come in. |
