Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-02-01T07:54Z ( SOHO: LASCO/C3 )
All Detecting Spacecrafts:
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-02-01T07:54:00-CME-001 (version 1)
Note Keyword:
DPL: CME exhibits dimpled front
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is visible to the NW in SOHO LASCO C3 and STEREO A COR2 imagery (SOHO LASCO C2 is unavailable due to an ongoing campaign). There is a data gap in STEREO A COR2 imagery before the start of this CME which prevented COR2 from seeing the front of the CME. The source of this CME is a filament eruption and moving/opening field lines seen along the NW limb in SDO/AIA 304 and 171 starting around 2023-02-01T05:30Z. However, an eclipse occurs during observation of the eruption so it is not fully visible. GOES SUVI 304, 171, and 284 have views of the eruption as well. A small EUV wave is visible in GOES SUVI 284 following the start of the eruption.

These parameters are based off of a fit of a majority of the CME. Due to the dimpled front shape (heart-shaped front), it was difficult to fit the entire CME in measurements. This measurement excluded the top left portion due to this. The Right Hand Boundary was followed throughout the measurement in order to use STEREO A COR2 imagery since the front was out of the field of view. Due to this, these parameters have a higher uncertainty associated with them. The leading edge was visible and also tracked in the fit for SOHO LASCO C3 images. |
