Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-07-21T04:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-07-21T04:24:00-CME-001 (version 1)
Source Location: N15W73
Active Region Number: 13744
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Bright CME seen to the WNW in all coronagraphs. The source is an eruption from AR 3744 and M1.4 flare which peaked at 2024-07-21T03:55Z (best observed in SDO AIA 131). Also observed in SDO AIA 171/193/211 as rapidly opening field line movement starting around 2024-07-21T03:28Z followed immediately by a post-eruptive arcade.

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 75.0 15.0 598.0 C 26.0 2024-07-21T10:41Z Well triangulated measurement between SOHO LASCO C3 and STEREO COR2A using the source of AR 3744, finding a great fit at these coordinates. This measurement excludes C2 and some earliest C3 and COR2A frames to provide a more accurate final speed, as some acceleration was observed in the measurement with every frame. 1: Result 1 (2.0 AU)
