Activity ID: 2025-12-31T14:00:00-CME-001 (version 1)
Source Location: N24E20
Active Region Number: 14324
Note Keyword:
3P: 3-part structure CME
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Partial halo CME visible to the NE in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. It is associated with an M7.1 flare from AR 14324 (N24E20) peaking at 2025-12-31T13:51Z. Eruption with EUV wave, dimming, opening field lines, and post eruptive arcades are best seen in SDO AIA 193 imagery. The eruption is also visible near the east limb as seen from STEREO A EUV imagery.

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 |
