Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-04-15T11:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-04-15T11:53:00-CME-001 (version 1)
Note Keyword:
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Fast CME to the W/NW in STEREO A COR2 imagery appearing more as a partial halo to the W/NW in GOES CCOR-1 imagery. There is currently a data gap for this event in SOHO LASCO C2/C3 imagery. The source is a filament eruption visible along the limb of STEREO A EUVI 304 imagery as well as in GOES SUVI 304 to the NW starting around 2026-04-15T11:15Z with associated moving/opening field lines in GOES SUVI 284 and STEREO A EUVI 195. Using available Solar Orbiter imagery, it appears the source may be near N05W150 (possibly AR 14409).

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 |
