Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-19T18:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2026-09-19T18:48:00-CME-001 (version 4)
Source Location: N14E90
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint, minor CME with an unclear front seen to the E-NE in SOHO LASCO C2. Not seen in other coronagraphs. Its source is the long duration C3.3 class flare from unnumbered AR rotating onto disk (N14E90) peaking at 2026-09-19T18:17Z. There is also an associated opening of field lines on/behind the E limb seen in SDO AIA 193 and a minor prominence/ejecta seen in SDO AIA 304/171 starting after 2026-09-19T18:10Z. The initial front is followed by a series of outflows.

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
