Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-09-03T12:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-09-03T12:48:00-CME-001 (version 1)
Active Region Number: 13413
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
LS: Loop and Shock Candidate
Note: This CME is visible to the W/SW in SOHO LASCO C2, C3, and STEREO A COR2 imagery with possible overlap of a faint/slow CME to the SW. The source of this CME is two back-to-back C-class flares from AR13413 from beyond the NW limb as seen in SDO/AIA 131 starting around 11:30Z with rising loops visible in SDO/AIA 171 starting around 12:00Z.

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
