Coronal Mass Ejection

Activity ID: 2023-11-29T13:48:00-CME-001 (version 1)
Source Location: S06W09
Active Region Number: 13500
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Faint CME seen to the SW in all coronagraphs. The source is uncertain, with the best candidate being a large area of slow dimming from AR 3500 that begins around 2023-11-29T05:31Z and persists until around 2023-11-29T11:00Z, best observed in SDO AIA 193/211. The dimming extends approximately from W05->W12 and N02->S10. This potential source was determined through measurements in swpc_cat as a viable source based on the visual fit with SOHO LASCO C2/C3 and STEREO COR2A, but it is noted that the time between the dimming and first visibility in the coronagraph is decently far.

This analysis is very uncertain since we were not able to connect this CME in coronagraphs with any lower coronal signatures in EUV instruments (although there is a lot of small flaring in Active Region 3500 in the morning of 2023-11-29). This analysis is based solely on the fit in swpc_cat with two coronagraphs, however the fit strongly suggests the resulting latitude and longitude, which happen to correspond to the location of Active Region 3500 at the time. |
