Sat Feb 17th & 18th with Nth Polar Cap spot

Imaged Saturn in reasonable seeing Feb 17th, the North Polar hexagon is well defined but no other discrete detail stands out for me in these data.

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

Trevor
