I made an observation of Saturn on March 27, 2009 (03:00 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain under average seeing conditions (with moments of steadier seeing). A few satellites were visible at the time.

Date (U.T.): March 27, 2009
Time (U.T.): 03:00
L1 235.2, L2 258.6, L3 085.0
De -3.3, Ds -2.2
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 115x, 253x, and 322x
Seeing (1-10): 5 (moments of 6-7), Antoniadi (I-V): III
Transparency (1-6): 4

Notes:
South Polar Region (SPR): Appears dark to dusky (3-4/10) without any other detail visible within.
South Temperate Zone (STZ): Appears shaded (6/10) without any other detail visible within.
South Temperate Belt (STB): Appears dusky (4/10) and thin.
South Tropical Zone (STrZ): Appears shaded to bright (6-7/10) without any other detail visible within.
South Equatorial Belt (SEB): Appears dark to shaded (3-4/10) with dark (3/10) condensations noted within the northern and southern components of the belt (SEB-N and SEB-S). A thin and bright (7/10) zone is noted between the two components.
Equatorial Zone (EZ): Appears bright (7/10) without any detail visible within.
A thin and dark (3/10) shadow of the rings appears over the globe.
North Tropical Zone (NTrZ): Appears shaded to bright (6-7/10) without any detail visible within. The northern half of the zone exhibits a pastel bluish color.
North Equatorial Belt (NEB): Appears dark to dull (3-5/10) and thinner than the SEB. No detail is visible within the belt.
North Temperate Zone (NTZ): Appears shaded (6/10) and exhibits a pastel bluish color. No detail is visible within.
North Polar Region (NPR): Appears dark to shaded (3-4/10) without any detail visible within.

Satellites (preceding to following):
Rhea (9.6m), Dione (10.3m), Tethys (10.1m, south of the preceding ansa (preceding edge of ring)), and Titan (8.2m)

The best of luck in your own observations/imaging of Saturn.

Frank, Juha, and Tommy

Thank you for your kind compliments on my latest Saturn observation. The ringed planet is always a sight to behold (and render). Saturn was beautiful floating in the eyepiece field. The best of luck in your own observations of Saturn.

Carlos,
Outstanding observation and drawing as usual. With the detailed report it will make the sketch even more relevent as the planet becomes more oblique again. I am going to have to follow your example and do a much better job of observing and recording in the future. Thanks for the posting.

Sol,

Thank you for the compliment on my Saturn observation. I was impressed with the detail visible and bluish hue over the northern hemisphere. The addition of the satellites is also a treat. I cannot but be inspired when you post your own outstanding observations of Saturn. The best of luck.

Carlos,

It was both you and Eric Jamison that got me inspired to start sketching in the first place.

Roland,

Thank you for the compliment on my Saturn observation. I look forward to your (and Linda's) wonderful observations in the future.

Sol- I have been fortunate to have had wonderful mentors in the past that have guided me into the observer that I now am (e.g. Charles F. Capen, Don Parker, and Jeff Beish). We all can learn new things from one another. I am lucky to have wonderful friends on this forum to share my observations with.

Carlos

Carlos, These are terrific sketches of Saturn and moons! Your rendition of the bands and their colors are spot on. Lovely near "edge on" rings. Great report as always. Thanks for the view!
