Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-02-23T11:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-02-23T11:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: Very faint CME front seen to the N/NE in SOHO LASCO C2, C3 and STEREO A COR2 imagery. The start time of the feature may be off slightly due to data gaps in SOHO imagery. The first clear image of the front in STEREO A COR2 imagery is around 13:00Z. The potential source for this CME is a filament eruption seen along the northeastern cap of the solar disk starting around 2023-02-23T09:30Z. Additional activity is seen across the Earth-facing disk in the form of a filament moving from a SE footpoint to a NW footpoint before becoming untraceable. It is unclear if this filament is also associated with this feature or if it did not fully lift off.

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 on a StereoCAT measurement of the faint front using the black/white boundary of the available difference imagery in STEREO A COR2 images and the whitelight imagery of SOHO LASCO C3. There is a high level of uncertainty with these parameters due to the faintness of the front. |
