Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-09-18T12:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-09-18T12:09:00-CME-001 (version 3)
Note Keyword:
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Ear-shaped partial halo CME in the NW (or two CMEs moving in unison), with no clear source found, so it is likely backsided. To support the backsided assumption, there seems to be a faint opening of magnetic field lines/restructuring of magnetic field seemingly far behind the NW limb seen in GOES SUVI 284 around 2023-09-18T12Z. Although there is no clear front-sided source, there seems to be minor flaring in AR 3433 (delayed to a plage) and AR 3429 and there is seems to be a post-eruptive arcade that fills a dark filament channel W centered (N10W50) of AR3439 by 12:55Z. There is also a very minor eruption on the NW limb N of AR 3225(N23W81) starting at in AIA 304. These are very minor coronal signatures though.

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 |

Plane of sky analysis, because of uncertainty of the source, which we think is more likely backsided. |
