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.
Another excellent capture and all those red squares on the drift chart Trevor leave us in no doubt who the Saturn master is. Looking forward to Saturn next year when I hope there is something interesting again.
Cheers, Phil
Thanks Phil, Saturn has always been my primary interest since getting into planetary imaging. So much has happened since imaging my first SED's related storm early in 2008. That initial work led directly to my first contact, via Dave Herald, with Anthony surely the doyen of planetary imaging in this country. As for the drift chart, I greatly appreciate the data points contributed by all in our group. I do get a lot of opportunities to collect data out here at Broken Hill. The geographic separation between Broken Hill, Murrumbateman & Rubyvale should mean that generally at least one of us will be able to get time specific data when required and with Chris in the Philippines and Damian's data from Barbados it certainly helps filling in the gaps.
