Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2021-09-05T21:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2021-09-05T21:36:00-CME-001 (version 3)
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
EUVW: EUV Wave
Morphology Keyword:
Note: The observed CME starts to faintly emerge from the SE quadrant of SOHO LASCO C2 starting at 2021-09-05T21:36Z, after which a halo feature becomes visible towards the south starting around 2021-09-05T23:36Z. May be associated with the combined eruptions from AR2865 at 2021-09-05T17:54Z (associated with a B7.9 flare) and from AR2864 at 2021-09-05T18:48Z (associated with a B7.0 flare).

CME Analysis M2M_CATALOG SH true SWPC_CAT 0.0 7.0 537.0 C 45.0 2021-09-06T04:21Z Analysis of this CME was difficult due to the faint feature of the partial halo to the south of SOHO LASCO C2/C3 coronagraphs. The best fit for this CME led to speeds ranging from 450km/s to 550km/s. The best fit due to wide width was provided here and used to simulate this CME. 1: Result 1 (2.0 AU)
