The winds finally died down and the seeing was unusually good at times. i was able to use powers of x250 and x312 to make some reasonable drawings. I also was able to make intensity estimates in IL,W80A and W11. My impressions of the globe and rings were as follows:
Paul G. Abel(203mm reflector)|
Globe: SPR rather dark a STB and SEB seemed to be present. The STropZ and EZ(s)(?) were also bright. The EZ(n) contained a yellowish EB,a lovely light egg shell colour was present in the zone. NEB was a double feature with NEB(n) being the most well defined of the two components and rather dark. The storm was near the proc limb and rather bright,it seems to me to be in the lower (northern) part of the NTropZ and cuts into the NTB and possibly the NTZ. Also of interest was a veil structure connecting the NTB with the NEB(n),spanning the NTropZ. The NTropZ and NTZ were rather bright (the NTZ in a more uniform manner) and I was under the impression that the NTB contained darker (and thicker?) sections. NNTB seemed uniform and a the NPR were dark and dusky.
Rings: A-Ring darker at it's outer edge and still a light brown colour. Cassini Division still fairly easy to see. The B-Ring was of interest. The B1-Ring appeared to be brighter than the last time I looked at it,and was a white-light grey colour. The B2-Ring seemed irregular in places- at the ansae centre it seemed as though the B1-Ring cut into it (as shown in drawing 1). I am reasonably confident that there were darker sections present in the B2-Ring (spokes?) as shown in drawings 1 and 2. C-Ring seen,best observed at ansae centre.
2315UT: #80A(Blue) Tethys looked distinctly brighter in this filter compared to IL.
2317UT: #47 (Violet). No disk deatils are discernable in this light but it is clear that the B1 Ring is the brightest feature on Saturn.
2323UT: #25A (Red). The belts come out well in this light,and I was impressed enough to make a drawing with this filter (drawing 2). I think the spokes in the rings may come out better in this light too,but the seeing has dropped of a little so i cannot be certain.
By 2334UT some kind soul had let it slip to Spode that I was having a good night and a single cloud parked itself over Saturn the rest of the sky was (naturally) clear. However by 2339UT,clouds came in proper and I had no choice but to retire for the night.
