Sat Nth Polar spot Oct 14th

Targeted the +63 dark spot Oct 14th. As currently I only have a window of approx 30 minutes and shrinking to capture Saturn data, having the longitude of the polar spot available is providing rather scant opportunities. My WinJUPOS generated ephemeris has been a great help.

I only had one 685nm IR data set that resolves the spot nicely, the first 9 minutes of the session.

I measure the spot to be at Lat +64.2 L3 301.2
The drift rate continues to be very stable at approx -11.4 deg/day.

As this may well be my final Saturn data for this apparition I have attached my updated drift chart. This contains data from Anthony Wesley, Phil Miles, Damian Peach, Chris Go and myself.
