Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-11-20T00:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-11-20T00:12:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Likely filament eruption seen to the NE in all coronagraphs. The source is likely a piece of a larger filament that was responsible for CME 2023-11-19T21:24Z, as we observe the east-most part of that filament lag behind, deflect eastward, and erupt a bit later in SDO AIA 304 and GOES SUVI 304 around 2023-11-20T21:39Z. SDO AIA 171/193 also observe this motion well in the field line movement.
Source is a filament over the high NE limb, first seen erupting over the limb at 2023-11-19T20:49Z in SDO AIA 304 and GOES SUVI 304. Additionally observed in SDO AIA 171/193/211 as moving field lines at the same time. As the filament source is far-sided, we do not observe the source longitude, but it is estimated to span around E120-E160 at a high latitude prior to erupting. During the eruption, a piece of the filament lags behind and may be responsible for a separate CME: 2023-11-20T00:12Z shortly after.

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 measurement as we do not observe the source of this filament erupting on the far-side of the disk over the NE limb. |
