Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-20T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-05-20T21:12:00-CME-001 (version 1)
Source Location: S28E33
Note Keyword:
COL: Possible collision with previous CME
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Faint CME to the SE (the second, more S in a pair of closely following faint and narrow CMEs). Its source could be the continuing eruption SE of AR 3688 seen after 20Z as dimming seen as enlarging the SE CH to the south of the Active Region. This dimming is centered at S28E33.

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
