Saturn polar spot Sept 5th

Imaged the +63 dark spot Sept 5th capturing it close to the CM so have an accurate data point for my drift chart & spreadsheet. Have a 685nm IR animation that I have attached here. This animation is of two data sets centred 32 minutes apart and shows the spot moving across the CM. I measure it in the 09:28 UTC data to be at Lat +64.1 L3 33.8 degrees. The L3 drift rate continues to be approx 11.4 degrees/day.



Regards
Trevor
