Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-03-17T10:58Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2023-03-17T10:58:00-CME-001 (version 2)
Source Location: S40W30
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
Morphology Keyword:
F: Flux Rope
Note: This CME overlaps the CME first seen in SOHO LASCO C2 at 2023-03-17T10:30Z to the SW. There are currently ongoing campaigns impacting the amount of available imagery for the SOHO LASCO C3 and STEREO A COR2 coronagraphs. The source of this CME is a large filament eruption seen in SDO/AIA 304 and GOES SUVI 304 starting around 2023-03-17T08:50Z with full lift off by 2023-03-17T12:17Z. The filament has it's largest mass centered around S40W30, but stretches between the longitudes of 0 degrees to 40 degrees and the latitudes of -20 degrees to -50 degrees.

These parameters have a higher degree of uncertainty due to limited imagery and the overlapping CME features between this CME and the CME seen at 2023-03-17T10:30Z. The more pointed portion of the front was excluded in this measurement in order to track a more consistent front throughout the measurement. |
