Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-09-17T13:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2

Activity ID: 2023-09-17T13:38:00-CME-001 (version 2)
Source Location: S40W90
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
KEY: Keyhole-hole shaped CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Beautiful bright 3-part CME with the the source a slowly developing eruption of a large filament off the SW limb (~S40W90), with a faint opening of field lines seemingly behind the limb seen in AIA 171/193/304 indicating that the eruption might be more backsided (behind the limb). The filament eruption is best seen in its earlier stages in EUVI A 304 and in its later stages in GOES SUVI 304. The eruption is seen starting after 2023-09-17T10:45Z.

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 |

Very approximate and imperfect analysis based on the assumption that the filament is erupting off the SW limb, however based on the coronal signatures it is more likely to be somewhat further behind the limb, just not clear at what longitude. Compared to the filament's latitude (40 deg South) the resulting CME latitude seems to be 20 deg more southward, indicating southern deflection. |

A highly approximate measurement, assuming the shock of the CME is backsided. |
