Attached is my first Saturn observation of the 2013-14 apparition.
Alas Saturn is now low down in Libra and so I have to wait for the planet to clear the houses before
I can look at it from the observatory. As a result,I have not been able to make an observation of it
until after opposition.
Although the seeing was poor,there were a number of features present:
*NEB seemed to be a double feature
*Both a NTB and NNTB belt was present
*NTropZ and NTZ seemed to have a definite greenish hue
*NPC dark,slightly bluish.
*A-Ring grey in colour.
*B-Ring bright,interestingly there seemed to be a brownish cast to the B-Ring close to the C-Ring.
*C-Ring not an easy feature.

Imaged Saturn last night in variable seeing. Amongst my data are some rather nice R,IR & RGB data sets.
I note a bright elongated feature at the latitude of the Great Storm. I measure it to be centred at approx L3 319 Lat +46.5
This feature is best seen in my R channel data from 13:04:54 and 13:26:54 UTC. It is also visible in my RGB data from 13:10 & 13:32 UTC,
It can also be seen in polar projections of my 13:04:54 R channel and 13:10 RGB.
All of the data from this session I have uploaded,I also attached an R channel & RGB animation that shows the feature I refer to,most prominent in the R data.
I measured the bright spot in Damian's stunning RGB from Barbados April 14th (L3 195) thinking I may have captured the same feature which could be elongated due to the seeing being significantly inferior to that experienced by Damian in Barbados. The measured L3 from my data varies considerably from the spot in Damians image,(1 month on) in excess of 200 L3 degrees so this must be a different feature.

Seeing was good for the altitude last night,a fairly slowly undulating but
sharp image on screen.
The RGB videos were 3 minutes each. Each has been referenced to one time and
derotation applied to make the RGB in WinJUPOS.
The Violet+IR image,also 3 minutes,taken a bit later,has also been used as a
luminance layer,without compensating for rotation,in the lower presentation.
The Encke division is visible on the left ansa but not right.
