Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-09-14T15:36Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

Activity ID: 2024-09-14T15:36:00-CME-001 (version 2)
Source Location: S18E55
Active Region Number: 13825

Note Keyword:

3P: 3-part structure CME

FOV: Front Bright front; may be evidence of pileup

HAL: Halo CME

OFL: Outflowing material at the back of the CME

Source Signature Keyword:

FLR: Flare

PEA: Post eruption arcade

OFL: Moving/Opening field lines

BR: Brightening

DIM: Dimming

EUVW: EUV Wave

Morphology Keyword:

F: Flux Rope

FS: Flux Rope and Shock Candidate

L: Loop

LS: Loop and Shock Candidate

Note: Partial halo CME seen to the southeast in SOHO C2/C3 and not yet observed in STEREO A due to a data gap. Associated with a powerful X4.5-class solar flare from AR3825 (S18E55) and subsequent strong eruption, characterized by intense brightening in SDO 131 and fast ejecta seen best in GOES 284 as well as a large, fast EUV wave associated with the eruption traversing back towards the northwest seen best in SDO 171/193 that covers approximately half the solar disk.
