Good seeing this a.m. - but not good enough for me to detect the shadow of Enceladus which would have been approaching the p. limb at this time. However the shadow of Dione was quite well seen with the satellite close f. the limb also well seen. After a check with WinJupos I had a final (unsuccessful) attempt at Enceladus' shadow; made more difficult by my eyes constantly being drawn/lured to that of Dione!! I can say that I am finding the satellite shadows etc. much easier with this edge-on epoch than preceding ones - my first being that of 1966. I can most certainly put this down to using both eyes,i.e. the binocular attachment.
A small dark spot on the SEB(N) was timed on the CM at 05:38,L1=327o. The p.ansa of the rings noticeably brighter than f.
I have the colours saved for applying to the drawing; but I find that I need to do some re-calibrating (a long task!) of the monitor etc. after I inadvertently restored some defaults upon booting up to do this report! Perhaps can send later??

Here are some images from this morning under fair conditions. A transit of Dione was underway,with its shadow seen across the NEB. Note the bright storm in the STrZ latitude,and fainter white spot in the mid SEB.
Just a note that the bright spot seen in my Dec 7th images is located at L3=312 and lat -40. It will next be visible early thursday morning for UK based observers.

地上は東風の微風ですが、上空は小刻みに荒れています。
シーイング悪いせいか、環の輝きが少なくなった感じがします。

These images have S at top. They were taken soon after Damian's, and confirm the
details in his. Titan appears preceding Saturn just N of the ring plane. Dione
is visible transiting just N of the ring plane, and its shadow appears on the
disk preceding. A clear spot is present on the CM in the STrZ on the CM at
III=312, and a fainter spot is visible in the SEBZ. In the high-contrast red
image there may be some genuine finer detail as well: condensations on the NEB
and waves or projections on the SEB N edge, but one cannot be sure without a
time sequence.
