Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-13T15:05Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-12-13T15:05:00-CME-001 (version 1)
Source Location: N03W37
Active Region Number: 13514
Note Keyword:
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
Ha: Bright emission (likely H-alpha emission)
Source Signature Keyword:
DFLR: Double ribbon flare
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
O: Other
Note: CME seen to the west in all coronagraphs. The source for this event is potentially a large, but slow to evolve dimming region near AR 3514 best seen in SDO AIA 193/211. This dimming spanned approximately W20->W55 and N17->S11 at timestamp 2023-12-13T13:30Z, starting around 2023-12-13T11:31Z. Some additional field line movement is observed in SDO AIA 171, and some surface brightening in SDO AIA 304 at the same time as the dimming. In measuring this CME, some uncertainty in this being the source was noted however, as the longitudes of this dimming did not yield a good fit and the CME may have deflected westward if this is the source.

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 |

Measurement using the dimming region near AR 3514 that spanned as far as W55 as the source to begin. Found that longitudes >W55 yielded better triangulated fits between SOHO LASCO C2/C3 and STEREO COR2A imagery, with the best fits in a range of W59-W65 showing some westward deflection. Potential fits beyond the limb did not triangulate well between coronagraphs, corroborating this observed deflection from the on-disk dimming region. |
