DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-10-05T03:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-10-05T03:12:00-CME-001 (version 1)
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
Ha: Bright emission (likely H-alpha emission)
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: Beautiful prominence eruption seen to the NE in all coronagraphs. Source is a prominence that was hanging well above the solar surface, almost out of SDO AIA 304 and GOES SUVI 304's view before erupting. The prominence is best seen in GOES SUVI 304 and SDO AIA 304, resting close to the NE limb throughout 2023-10-03 -> 2023-10-04 and beginning to separate and rise further around 2023-10-04T18:04Z. It slowly rises higher in altitude until about 2023-10-05T01:16Z, when it finally splits apart into an eruption, also observed in SDO AIA 171/193/211 as some field line movement around the same time. As the prominence rose so high before eruption, pinpointing a surface lat/lon is almost impossible. We do know it took place on or near the NE limb at a high latitude before deflecting a little southward as the material expanded within SOHO LASCO C2's FOV.

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 |

As the CME expanded and accelerated within SOHO LASCO C2's view, only C3 frames past 2023-10-05T07:18Z were used for this plane of sky. Some slight southward "deflection" is noted, as the CME began at a higher latitude but a lower latitude was required to fit the shape in later C3 frames versus C2--this is visually noted as well by watching it evolve through coronagraph imagery. |
