Saturn 2010 GWS AV Nov 4th

Hi All,

Imaged Saturn November 4th 2021 targeting a CM transit of the 2010 GWS AV, these data provided an early birthday present. The transit should have occurred at 09:14 UTC just at Sunset with the sky still quite blue. Saturn was not yet visible at that time but Jupiter had just popped out so slewed from Jupiter to Saturn using my optical finder. Have very well resolved the AV in 685nm IR data with the R and RGB data just providing a subtle glimpse of the AV. The IR data provided a very good data point for my spread sheet and drift chart for the AV. I measure the AV to be at approx Lat+41.6 L3 288.5 a mid latitude bright spot is also resolved in the R data at approx Lat+30 L3 336.5. The IR animation reveals considerable low contrast detail within the EZ and the RGB polar map nicely resolves the vertices of the polar hexagon. All data from this session has been uploaded to PVOL.
