Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-11-29T13:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
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.

CME Analysis M2M_CATALOG LE true SWPC_CAT 23.0 -16.0 430.0 S 16.0 2023-11-29T20:49Z 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. 1: Result 1 (2.0 AU)
