Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-09T12:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-12-09T12:48:00-CME-001 (version 1)
Source Location: S28E52
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: Faint, fuzzy CME to the SE seen in all coronagraphs. Source is an on-disk filament near the SE limb, spanning approximately S25E55 to over the SE limb around S45 at 2023-12-09T07:51Z before erupting, best observed in SDO AIA 304 and GOES SUVI 304. This filament rises and twists for a while, losing a lot of material back to the surface (can be seen hitting near the limb) and "fizzling" out in GOES SUVI 304's wider FOV. This CME is difficult to track in coronagraphs, likely due to the nature of this eruption. Also observed as some dimming centered around S28E52 in SDO AIA 193 and field line movement in SDO AIA 171.
