Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-21T20:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-05-21T20:24:00-CME-001 (version 2)
Note Keyword:
DFL: Likely deflection of the event within the FOV
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Filament eruption seen to the S in all coronagraphs. The source for this CME is a filament which is observed best in SDO AIA 304 and GOES SUVI 304's wider FOV over the far southern limb, in close proximity to the south pole. As such, narrowing down a longitude is difficult. This filament began to slowly lift off ~2024-05-21T14:00Z, erupting more explosively ~T17:00Z, and fiercely whipping around in the corona ~T19:00Z before fading away and leaving the FOV into this observed CME front.

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 given the uncertain source longitude due to proximity to the southern pole of the disk, and no available COR2A imagery. As such, the longitudes could technically vary wildly as they converge to the poles. The eruption is likely due south with parameters similar to this plane of sky, based on its evolution in EUV imagery. |
