Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-08-19T22:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-08-19T22:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: The third of three overlapping CMEs, seen to the Southwest in SOHO LASCO C2/C3 and STEREO A COR2. The source is widely and distinctly opening field lines from beyond the Southwest limb seen starting at 2024-08-19T21:54Z in SDO AIA 171/193 and GOES SUVI 284.

Measurement TypeCME measurement type: Leading Edge (LE), Shock Front (SH), Right Hand Boundary (RHB), Left Hand Boundary (LHB), Black/White Boundary (BW), Prominence Core (COR), Disconnection Front (DIS), Trailing Edge (TE).
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
