Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-21T19:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-11-21T19:24:00-CME-001 (version 1)
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
US: Unknown and Shock Candidate
Note: Large, halo CME is visible to the N/NE in SOHO LASCO C2/C3, GOES CCOR-1, and W/NW in STEREO A COR2 imagery. The source of this CME appears to be far-sided with faint field line movement and possible EUV wave visible in GOES SUVI 284 to the N/NW starting around 2025-11-21T19:42Z. Filamentary material is also visible to the NE in GOES SUVI 304 starting around 2025-11-21T20:00Z which may or may not be associated with this CME.

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 |

Parameters based on best fit of the BULK of the CME, however the fit is better in STEREO A COR2 imagery than in SOHO or GOES imagery due to triangulation limitations. The half-width appears too wide for the visible bulk feature in SOHO LASCO C2/C3 and GOES CCOR-1 imagery compared to the visible bulk feature in STEREO A COR2 imagery. This may be due to limited viewpoints of the full CME. |
