Imaged Saturn this morning, the seeing was rather fast, typical of the effects of the jetstream but I was able to produce a couple of acceptable images. I have attached 1 742nm IR & 1 RGB data set.
There is an interesting spot in the RGB which I have measured in WinJUPOS to be at approx Lat +48 degrees L3 48 degrees. As my IR was 3 x 3min data sets combined & derotated and the RGB is 4 consecutive data sets over 23 min's combined & derotated, the time between the midpoint of the IR and mid point of the RGB is 21 minutes. I think there is a hint of the spot actually showing up in the IR as well when considering the amount of rotation that would have occurred between the IR & RGB.
Back on Dec 29th 2012 I imaged a similar spot, then it was at approx Lat +46 degrees, L3 39 degrees. Looking at the stated drift rate for that Lat given in WinJUPOS of .370 degrees/d that particular spot would have drifted 9.25 degrees which seems to line up nicely with the spot in this mornings data.
Thanks for looking
