Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-21T20:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-21T20:24:00-CME-001 (version 2)
Source Location: N24W135
Active Region Number: 14246
Note Keyword:
GAP: Data gap
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Full-halo CME seen to the NW in SOHO LASCO C2/C3 and GOES CCOR-1. Not yet captured in STEREO A COR2 due to a data gap in STEREO A which began at 2025-10-21T19:38Z. Source is an eruption beyond the NW limb as seen in GOES SUVI 284/304, seen as a narrow piece of ejecta from beyond the NW limb and rapidly, widely opening field lines also from beyond the NW limb. Brightening from former AR 14246 (N24W135) can be seen in the one frame of STEREO A EUVI 304 available in real time so far. (Note that MAVEN spacecraft detected an approximate equivalent of X1.7 flare peaking at 2025-10-21T20:28Z).

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 |
