Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-15T12:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-02-15T12:24:00-CME-001 (version 1)
Note Keyword:
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
Note: CME first seen to the SW partially into the FOV of SOHO LASCO C2 starting around 2026-02-15T12:24Z. This CME is also seen to the SW in GOES CCOR-1, SOHO LASCO C3, and STEREO A COR2. The source of this CME is most likely a filament eruption from on/over the SW limb best seen in SDO AIA 193 starting around 2026-02-15T10:50Z. This filament eruption can also be seen in STA EUVI 195 starting around 2026-02-15T11:25Z from the vicinity of former AR 14371. The filament and associated, subsequent dimming spans approximately W85 to W100.

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 |
