Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-09-09T07:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2022-09-09T07:24:00-CME-001 (version 2)
Note Keyword:
3P: 3-part structure CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: A faint CME in SOHO white light and running difference imagery which is seen as even fainter in STEREO A imagery with no true leading edge to analyze. It is directed mostly to the north in SOHO imagery and to the north and east in STEREO A. While the coronagraph imagery seems to suggest that the CME source is located on the Earth-facing disk, a preliminary triangulation using SWPC_Cat results in a broad area on the Earth-facing disk where no source seems to actually erupt. The analysis is therefore pretty speculative. The CME overlaps a few other faint CMEs which increases the difficulty of the 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 |

A measurement of the CME bulk as the leading edge/front was too diffuse to accurately measure, especially in STEREO A coronagraph imagery. |
