Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-05-21T00:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2022-05-21T00:12:00-CME-001 (version 3)
Source Location: N18W31
Active Region Number: 13011
Note Keyword:
Faint: Faint event; may affect type assignment
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: The likely source is an eruption from AR3011 (N18W31) which was associated with a C5.2 class flare occurring around 2022-05-20T23:30Z. After the brightening, filament material is ejected to the north and west as seen in SDO AIA 304A. Soon after this eruption, a complex signature is observed in SOHO running difference imagery with a large, faint and fast shock on the order of >1000 km/s emanating to the north which may or may not be associated with this flare. A coronal hole located to the southwest of the active region(s) possibly producing the eruption may have deflected the ejecta in the northward and eastward directions.

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 |

Upon analysis, there are two eruptions present in SOHO running difference imagery, only the first of which, a narrower event, correlates with the Stereo A/COR2A imagery. Thus, the CME of interest is only seen in SOHO imagery and the filamentary material is largely deflected to the north and west as seen in SDO AIA 304. There is also a weak shock front produced to the north in SOHO C2 running difference imagery on the order of 1000 km/s which may or may not be associated with this eruption. |
