Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-14T17:38Z ( STEREO A: SECCHI/COR2 )

GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
Source Signature Keyword:
FLR: Flare

LS: Loop and Shock Candidate
Note: Bright nearly full halo CME with the bulk portion to the west in all coronagraphs. The source is a X2.8 class flare from AR13514 (N05W54) peaking at 2023-12-14T17:02Z. The source is visible across all SDO/AIA wavelengths with clear dimming signatures to the SE of the eruption in SDO/AIA 193, 171, and 211. These dimming's correspond with brightening seen in SDO/AIA 304. An EUV wave is clearly seen in SDO/AIA 193, 211, and GOES SUVI 284 traveling to the SE towards disk center and along the western limb. The EUV wave appears to correspond with a large shock in the coronagraph imagery. Post-eruptive arcades are visible around 2023-12-14T19:00Z in SDO/AIA 171.
Start time clarification: The first available frame for this CME is from SOHO LASCO C2 at 2023-12-14T17:24Z, but this entry was created and had notifications sent with only STEREO COR2A imagery available, hence the start time of T17:38Z.

If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME |

Updated measurement with the full SOHO LASCO C2/C3 downlink now available, which allowed for some better triangulation using SOHO LASCO C2/C3 and STEREO COR2A imagery far into the FOV. The measured longitude was found to be deflected slightly eastward from the eruption site, and particularly wide. In this later analysis we found it difficult to differentiate between the shock front and leading edge in available real-time imagery. |
