 DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-19T23:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-02-19T23:48:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: This CME is visible to the S/SW in SOHO LASCO C2, C3 and following a data gap in STEREO A COR2. The leading edge of the CME is very messy without a clear/defined front associated with it. The source appears to be a filament eruption beyond the SW limb starting around 2024-02-19T22:06Z as seen in SDO/AIA 304.

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

CME Analysis M2M_CATALOG TE true Plane-of-sky NONE -79.0 527.0 C 22.0 2024-02-20T07:28Z These parameters are based off of a plane-of-sky measurement of the trailing edge using SOHO LASCO C3 difference imagery. There was no distinct front to analyze at the beginning of the event, it became too diffuse/messy to track. A later, more defined trailing edge of the CME was used for analysis.
