Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-28T20:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-02-28T20:24:00-CME-001 (version 1)
Source Location: N40E20
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
JS: Jet and Shock Candidate
Note: CME first seen to the North by SOHO LASCO C2 beginning at 2026-02-28T20:24Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This event is not visible in STEREO A COR2 due to a data gap which began at 2026-02-28T19:23Z. The source of this CME is a filament eruption seen centered at approx. N40E20 with liftoff beginning at approx. 2026-02-28T19:48Z as seen in GOES SUVI 304. Dimming and field line opening seen in GOES SUVI 195 appears to suggest a strong Northern deflection of 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 |
