Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-10-01T23:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-10-01T23:09:00-CME-001 (version 3)
Source Location: S17E18
Active Region Number: 13842
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
FS: Flux Rope and Shock Candidate
Note: Developing CME with bulk seen predominantly to the southeast in early frames with a very faint, oval-shaped/asymmetric halo shock portion, associated with an X7.1-class flare and associated eruption from AR3842 (S17E18). Coronal signatures include an EUV wave and large-scale dimming in SDO 171/193 with magnetic field line movement off the southern and southeast limbs and dimming of footpoints bridging the Active Region 3842 (S17E18) in GOES 284.

CME Analysis M2M_CATALOG SH true SWPC_CAT -10.0 -12.0 963.0 C 60.0 2024-10-02T02:29Z Updated measurement with a lower half-width to try and more closely match the observed type II shock speed for this event of ~1200 km/s. A very approximate analysis based on the fit of the complex-shaped faint shock with two coronagraphs. 1: Result 1 (2.0 AU)

CME Analysis M2M_CATALOG LE true SWPC_CAT -19.0 -10.0 594.0 C 38.0 2024-10-02T04:22Z Updated bulk measurement based on the best fit between SOHO LASCO C2 and STEREO A COR2 imagery. This event is obscured by the pylon in SOHO LASCO C3 imagery so only early imagery in SOHO LASCO C2 was used in this measurement. Multiple measurements produced speeds ranging from 487 to 632 km/s. 1: Result 1 (2.0 AU)
