春霞のせいか透明度の極端に悪い空でした。
双眼鏡で位置を確認し辛うじて撮影出来ました。

Attached is a Saturn drawing made last night. Alas seeing conditions were not too good, although there were a few steady moments. Saturn's is now at B=17.5 and this was detectable compared to the last observation. Other points of interest include:
-Faint EB present
-NEB a most interesting feature- it is hard to be sure but it looked like there might be another component immediately north of the NEBs with a light zone in between. The dark belt then continues and seems to give way to a light (greenish?) NTropZ. There seemed to be a number of dark sublte structures in the NEB(s) and the NEBz, although conditions didn't allow these details to be recorded in any great detail.
-NTB hard to see, greyish colour.
NPR dark.
A-Ring seemed to be a greyish brown, B1-Ring was bright and white in colour, while the B2-Ring was detectable. C-Ring seen at ansae edges.
2335UT: Examined Saturn with my new W#21 filter. Interestingly, the A-Ring seemed to be darker in this filter, while the contrast of the Cassini Division seemed to be somewhat increased. The NEB was harder to make out, but the W#21 does seem to help stabilise the image a little in these conditions.
