Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-22T23:29Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-08-22T23:29:00-CME-001 (version 1)
Source Location: N10W32
Active Region Number: 13405
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: Ultra-faint CME seen primarily to the south and west, especially in SOHO LASCO running difference imagery after 2023-08-23T23:00Z. Likely associated with the M1.1-class flare from Active Region 3405 (N10W32) and sympathetic structure of U-shaped dimming seen south and east of the active region, possibly centered around S10W20. Analysis of this CME is very uncertain and speculative given geometry of observing spacecraft and faintness of the CME.

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 |

Speculative leading edge measurement using SOHO C2 with a focus on the south leading edge, but wide enough to encapsulate the western leading edge. |

A more central approximation of the source ascribed to the large dimming region. Leading edge follows the very faint southern portion but wide enough to capture the western edge as well. |
