SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-26T20:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint CME visible to the SW in SOHO LASCO C2 and C3 imagery. There is no STEREO A COR2 imagery available for this CME due to a data gap. The source of this CME is a filament eruption from the area of Active Region 14065 (S31W51) which is located in the middle of a large southern coronal hole. The filament eruption starts around 2025-04-26T19:00Z as seen in SDO/AIA 304, 193, 211, and 171 spanning the area of ~S30W45 to ~S40W55.

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
