Imaged Saturn Feb 18th in good seeing, believe I have recovered the long lived dark spot (cyclone) near the North Polar collar.
I measure it in my 685nm IR data s2016-02-18_18-38-54_ir_tba to be at Lat +61.1 L3 256
I added this data to my spreadsheet for this feature and the data points lines up very nicely on my drift chart, which I have attached
