Imaged Saturn October 2nd targeting the CM transit of the 2010 GWS AV. There was considerable cloud about but have good data at all wavelengths,especially the first 685nm IR of the session.
The AV is well seen prior to reaching the CM and also well resolved very near the CM albeit in cloud effected data. I measure it to be at approx Lat+42.8 L3 92.1
There is a lot happening in these data,all data well resolves the vertices of the north polar hexagon along with the north polar vortex.
The thin concentric bands within the NPR are well seen in IR with many spots resolved the most prominent being at approx Lat+72.8 L3 72.8 along with a chain of bright spots at approx Lat+ 64.6 L3 95.9,Lat+64.2 L3 84 & Lat+65.5 L3 73.7
R channel and the RGB data doesn’t have the resolution of the 1st IR data set,however if these data are zoomed there clearly are a line of three resolved bright spots just past the CM toward the P limb within the NPR at approx Lat+66.2 L3 78.4,Lat+66.7 L3 62.4 & Lat+66.8 L3 45.9 also an isolated bright spot at approx Lat+46.4 L3 79.9 the RGB data also resolves these features.
The IR measurements were done on the IR from 08:59 UTC all measurements were done utilizing a zoom factor of 2.05 within WinJUPOS.
I have solid data for the AV through 2019 starting with the HST OPAL data June 20th and have regularly captured it through to this Oct 2nd data. I had been working with an approximate drift of -1.525 degrees / Day but have refined that further to now be approx -1.4650 degrees / Day.
