Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-25T12:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-25T12:36:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Bright and slow CME visible to the SE in GOES CCOR-1, and for a frame in SOHO LASCO C2 before a data gap starting at 2026-03-25T12:36Z. It is also visible due S in STEREO A COR2 imagery. The source is a filament eruption visible along/just beyond the SE limb in GOES SUVI 304 with associated moving/opening field lines in GOES SUVI 284 starting around 2026-03-25T07:00Z.

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 |
