気流は下の上でしたが、透明度が悪くて北極星が肉眼では見えない状態でした。
眼視400Xではまあまあの見え方でしたが、撮影では露出不足で悲惨でした。

A most interesting observation. The sky was dark and transparent, although seeing conditions veried between good and poor! I was defeated by clouds at 2344UT, but I managed to get a drawing and intensity estimates. Of most interest tonight was the STropZ and the A-Ring...
Globe: SPR dark and dusky, perhaps a SPB was present but I am not at all certain of this. STZ fairly bright and yellowish in colour, the STB could be seenw as gray in colour.
Interestingly, the STropZ seemed to be much brighter tonight than before and seemed comparable to the EZ(N). The yellowish colour associated with the zone also seemed to have gone and instead it appeared a creamy white colour. This was the case at both 250x and 312x. SEB double, but SEB(S) very difficult at times. EZ(S) fairly bright and a fairly strong yellow colour. EB suspected and appeared to be a brownish colour.
EZ(N) a bright while zone, and NEB was a double feature with NEB(S) being the darker of the two components tonight- some irregulairties present on the southern edge of NEB(S)? NTropZ and NTZ of the same brightness and colour and only seperated by a dim NTB. NPR dusky and vague.
Rings. The B-Ring appeared to be yellowish in colour tonight, and the Cassini Division could be glimpsed. It did appear that the A-Ring on the left of the planet (Proc. side) was a bluish colour while on the other side it was gray- most unusual; this could be a seeing artefact of course.
