DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-03-09T13:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-03-09T13:48:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
SUR: Surge-like eruption
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
LS: Loop and Shock Candidate
Note: This CME overlaps the CME first seen in SOHO LASCO C2 at 2023-03-09T13:25Z and may include overlapping features in the analysis. This CME appears as a partial/full halo with a bulk portion to the SW. There may be a separate filament core portion included in the analysis of this CME that is associated with a separate filament eruption seen along the western limb with the lower footpoint portion holding onto the disk a bit longer than the northern portion. This is most clearly visible in GOES/SUVI 304 starting around 2023-03-09T13:49Z. Moving/opening field lines are also visible in SDO/AIA 171 along the W/SW limb in a surge-like eruption with an associated EUV wave in the corona limb material starting around 2023-03-09T13:16Z.

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 |

These parameters are based off of the best fit of the faint more southern shock feature and bulk seen to the SW in SOHO LASCO C3 and STEREO A COR2. There is a higher degree of uncertainty with these parameters due to the overlapping nature of one or more CMEs. |
