Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-01-23T19:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
Activity ID: 2023-01-23T19:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
Note: Fairly wide and faint CME seen to the NW in SOHO LASCO C2, C3 and to the North in STEREO-A COR2 imagery. There is no clear source for this CME. STEREO-A has imagery available for most of this event, but a data gap cuts off the CME before it exits the STEREO-A COR2 field of view.

The List of CME Analysis already entered:
Event Type Catalog
Data Level"data level" based on how the measurements were derived. 0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis.
Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME

CME Analysis M2M_CATALOG 0 true SWPC_CAT 161.0 28.0 713.0 C 31.0 2023-01-24T00:39Z These parameters are based off of the best fit of the CMEs leading edge and visible width in difference imagery. It is possible this CME could be wider than these parameters. Measured longitudes had minimal variation between 160 and 165 degrees. 1: Result 1 (2.0 AU)
