Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-11-18T12:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2022-11-18T12:00:00-CME-001 (version 1)
Source Location: N20W35
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
Note: CME appearing after a data gap in the NW in SOHO LASCO C2 (with the CME front already beyond the FOV). CME is partially obscured by the previous CME, but the front is seen clearly in C3. The CME is not seen in COR2A b/c of a data gap from 2022-11-18T07:53Z to 16:23Z. Possible source of the CME is the C5.1 class flare from the area around N20W35 peaking at 2022-11-18T11:28Z and the associated eruption seen as a relatively minor dimming and an EUV wave.

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 |

Analysis performed with one coronagraph (SOHO LASCO C2/C3) based on the source location (of the associated flare and eruption). Analysis is approximate both because it could not be confirmed with STEREO A COR2 due to a COR2 data gap from 2022-11-18T07:53Z to 16:23Z, after which the CME may have already exited the FOV of COR2, but also because this faint CME is partially overlapping with the previous CME, making analysis uncertain. |
