Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-11-17T02:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-11-17T02:48:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
BR: Brightening
Morphology Keyword:
O: Other
Note: Faint CME seen to the SE in all coronagraphs. No clear source for this event is observed, with the only notable signature being some brightening of existing field lines loops over an unnumbered AR sitting on the SE limb starting around 2023-11-17T01:24Z. There is some ongoing, slow field line loop expansion observed for several hours prior in GOES SUVI 284 over the NE limb, but that appears too slow to be associated with 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.
