Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-07-17T07:16Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-07-17T07:16:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Full-halo CME seen to the west in SOHO LASCO C2/C3 and STEREO A COR2. CME visible for only two frames in C3 due to reduced cadence. The source is likely on the far-side, as evidenced by flickering field lines off the northwest limb seen best in GOES-18 SUVI 195/171, and widely opening field lines seen off the northwest limb in GOES SUVI 284 starting at 2023-07-17T06:56Z.

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.
