Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-04-09T09:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-04-09T09:48:00-CME-001 (version 1)
Source Location: N20W65
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Large bright CME seen to the NW in SOHO LASCO C2, C3, and STEREO A COR2. The source appears to be associated with a filament eruption (best seen in SDO/AIA 304) followed by a large area of dimming (best seen in SDO/AIA 193 and 211) and post-eruptive arcade (SDO/AIA 171). The eruption looks like it could stretch across multiple longitudes (~50 to 90+).

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

CME Analysis M2M_CATALOG LE true SWPC_CAT 76.0 16.0 655.0 C 45.0 2023-04-09T15:47Z These parameters are based off of the best fit between SOHO LASCO C3 and STEREO A COR2 imagery, with keeping the source location in mind. Additional measurements at longitudes between 60 and 125 degrees yielded roughly the same velocities. All measurements appeared to be relatively good fits for the features, making it difficult to choose which measurement had the best parameters. Using higher longitudes gave more inclusion on the fainter features on the north side of the CME while the longitudes closer to the one used above provided better lines of best fit. 1: Result 1 (2.0 AU)
