Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-21T16:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-02-21T16:12:00-CME-001 (version 3)
Source Location: S35E90
Note Keyword:
3P: 3-part structure CME
DFL: Likely deflection of the event within the FOV
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright high southern latitude CME with a narrower bulk and a wider fuzzy shock front. Its source is the eruption (ejecta seen in AIA 193/171/304 after 2024-02-21T15:39Z) happening seemingly just beyond SE limb, especially judging by the posteruptive arcades peaking from behind the SE limb very soon after the initial eruption. There is also an opening of field lines seen in 193/171. The eruption is centered at apparent latitude of S35, but the CME seems to have a southward deflection as seen in coronagraphs. The source might be the returning old AR 13575 (currently at the estimated longitude E90). The (start of) the CME is covered by a data gap in STEREO A COR2 starting at 2024-02-21T13:23Z.

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 LE true SWPC_CAT -90.0 -61.0 880.0 C 31.0 2024-02-21T20:12Z Approximate measurement of the narrower brighter bulk of the CME based on swpc_cat analysis with one coronagraph (SOHO) as STEREO has a data gap since 2024-02-21T13:23Z. Since the source is not seen (behind the limb), the longitude could possibly be a little higher (maybe up to -100 degrees), but we are using the approximate longitude of old returning AR 3575 as the likely longitude.

CME Analysis M2M_CATALOG SH true SWPC_CAT -90.0 -58.0 947.0 C 48.0 2024-02-21T19:56Z Analysis of a fainter wider shock of the CME. The longitude could be higher (maybe up to -100 degrees). Not modeled Anna Chulaki on 2024-02-21T19:59Z
