Imaged Saturn June 7th in very good seeing, it is the best Saturn data I have captured since 2017. The North Polar Storm resolves into multiple bright cells instead of just a thin bright band, there is resolved detail and structure everywhere. This session produced a large body of hi-res data and all of it has been uploaded to the PVOL data base. Below I list the highlights.
Very hi-res data, particularly the IR. Bright spots within the North Polar Storm at approx Lat+65 L3 31.1, Lat+64.2 L3 54.6, Lat+65.5 L3 71.1, Lat+64.9 L3 85.6, Lat+64.6 L3 105.9, Lat+63.2 L3 130.2, Dark spot at approx Lat+61.1 L3 170.6.
Oval, possibly fossil of Great Storm at approx Lat+46 L3 77.9, I resolved a very similar feature at this latitude in 2018 on April 19th, May 14th, August 8th & September 16th.
Bright spot at approx Lat+30.6 L3 99.8.
Bright ripple on edge of EZ extending into NEB at approx Lat+15.5 L1 84.
Multiple features in EZ, two dark very narrow linear features with bright spots between them, I measure the brightest of these spots to be at approx Lat-0.2 L1 102.1
Every time I start blinking IR data sets I see more detail, when I get time I intend going back again through these data, this time I stacked 85% of all data but I think I could stack even more of it.
The IR animation is stunning, it represents 2 hrs of Saturn rotation.
