Please find attached my first Saturn observation of the current apparition. Conditions were rather poor at times with frequent passing cloud and haze. Seeing was fair,around AIII - AIV. Some interesting points to note:
Globe:
-The STB and SEB can now be seen properly after being obscured by the rings for many years. I did note that the SEB and STB had a bluish-grey cast to them while the STZ and SPR contained a greenish tine. Looking back at my log books I find that the northern hemisphere had this exact colouration when the tilt was B=-8°
-The EZ(n) was yellowish with a hint of a EB.
-The NEB was broad and contained two distinctive components. The NEB(s) seemed to contain some darker condensations.
-The NTB and NNTB were seen- the colours in the northern hemisphere were much warmer than those of the south.
Rings:
-The rings are now much narrower- the A-Ring was a brownish colour,the outer edges were darker in moments of good seeing.
-Cassini Division observed but was seen only at the ansae edge.
-B-Ring bright
-C-Ring was also seen.
Dione was due to pass behind Saturn later but cloud cover became total at 0025UT and no further observations could be made.

南中時，非常に良いシーイングであった。土星表面には顕著な変化は認められない。
Very good seeing at crossing the meridian. No significant changes were observed on Saturn's surface.
