Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-02T09:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-08-02T09:12:00-CME-001 (version 1)
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
LS: Loop and Shock Candidate
Note: This CME is seen as a halo CME with a bulk portion seen more predominantly to the west in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The more full halo portion is fairly faint in coronagraph imagery. The source of this CME is an S-shaped filament eruption stretching from roughly N10 to S15. There is clear dimming associated with this source as seen in SDO/AIA 193 starting around 2023-08-02T08:00Z. This dimming stretches from W10 to W30 within the N10 to S15 latitudes.

CME Analysis M2M_CATALOG LE COR true SWPC_CAT 26.0 -4.0 759.0 C 42.0 2023-08-02T13:43Z These parameters are based on the best fit of the bulk portion of the CME seen predominantly to the west in coronagraphs. Measured speeds ranged between 750 km/s to 850 km/s. This CME is measured with an approximated longitude due to a lack of stereoscopic viewpoints. Potential measured longitudes ranged between 20 to 30 degrees with ranges from 0 to -5 degrees in latitude. 1: Result 1 (2.0 AU)
