Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-10-02T18:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2023-10-02T18:24:00-CME-001 (version 2)
Source Location: S05E10
Note Keyword:
COL: Possible collision with previous CME
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Extremely faint CME with uneven front seen to the East in C2 and COR2A. Source is very uncertain, but one candidate is an area of very subtle dimming seen at 2023-10-02T16:54Z in SDO AIA & GOES SUVI 195 spanning from about N05E22 to N05E00(AR 13453) down to S10E00. Centered at about S05E10. This dimming is possibly associated with a C-class flare and small eruption from AR 13450 (S10E07) seen starting at 2023-10-02T15:54Z. Alternatively, the CME could be backsided but we were not able to identify any backsided coronal signatures for it. This CME overlaps with a previous slow outflow CME seen also to the East with a source more likely beyond the limb, further complicating 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 |

Very low confidence/uncertain analysis: this CME could easily alternatively be backsided. Leading edge is extremely faint and becomes diffuse halfway through COR2A field of view. Partial overlap with previous CME (also to the East, but likely farsided) makes it difficult to identify and track the whole of the faint leading edge of this CME. |

Uncertain POS analysis (uncertain in whether this feature is the leading edge of a CME since this event overlaps with an earlier CME in the East. |
