Please find attached a Saturn observation from the 8th June. Seeing was very poor and very little in the way of fine detail could be made out. ON the disk,the NEB was the most prominent feature.

Condition was perfect this evening! But taking these images was
exciting because there was a big thunderstorm about 10 miles north of
my location and this storm system was moving towards me!

These are some of my best images of Saturn. It was stormy north of
my location and this region of Saturn is also very stormy! The 64N
storm is just past the CM. In the IR,it is a dark spot. In visible
light it is dark spot while the area surrounding it has a reddish
color. This spot is not bright in CH4!
Note the 3 white spots on the NEB. Note also the thin reddish wavy
band on the EZ.

Targeted the long lived +63 anticyclone and extended feature. Have resolved it quite well near the CM. Have attached 3 of the 5 742nm IR data sets that were captured at approx 20 minute intervals,also a polar projection from the best data set. Have also attached an animation of all 5 data sets covering just under 1.5 hours of Saturn rotation which nicely highlights the anticyclone.

I've caught the polar spot again,but in a lot worse conditions than on the 1st. The seeing went from average to bad in a matter of minutes. There is a storm at 33,8N below the polar spot visible in the IR and the IR globe detail images.

Here are the Saturn images for June 8th 2015, taken in very average seeing
conditions with imminent cloud approach. This did not allow the use of
WinJupos compilations as only one capture in rgb plus 2 ir742nm captures
were possible, the second ir742 capture being significantly poorer than the
However, the Northern feature at +63.5°N was present in these images
allowing us to continue tracking the evolution of this very interesting
phenomenon & contributing to the PVOL team being given imaging time on the
HST to study said features, the results of which we look forward to seeing!
Although there are other features on Saturn's disk the Northern phenomenon
is currently our main focus: as expected the ir742nm image reveals this
feature in greatest contrast although the "R" channel gives possibly the
greatest definition. (also as expected! )
It was unfortunate that seeing & clouds prevented us from better outcomes
although the ir742nm North Polar projection is a reasonably good result: it
displays well some of the bright storm spots (cyclones) surrounding this
central dark feature...in this particular image our (rough) measurements of
the (central) dark feature/spot subtended over 6° in longitudinal coverage -
leaving aside the "disturbance' associated with this feature it is a very
large phenomenon indeed..!!!
