January 19, 2003, 3:00 - 4:30 UT, seeing 6 (good) transparency 3 - 4.
Astro-Physics 7.1" f/9 EDT refractor on homemade Dobsonian-style mount. Magnification 275x - 306x with Baader binoviewer.
The South Polar Region (SPR), the South South Temperate Zone (SSTeZ), and the South South Temperate Band (SSTeB) appeared green in color.
The South Tropical Zone (STrZ) appeared tan in color, and showed some variation in tone.
The South Equatorial Belt (SEB) was light brown and divided into the South Equatorial Belt south (SEBs), Equatorial Belt zone (white in color), and South Equatorial Belt north (SEBn).
The Equatorial Zone (EZ) appeared light yellow. A faint Equatorial Band (EB) was visible that divided the EZ into the EZ south (EZs) and EZ north (EZn).
The Crepe Ring was prominent and visible in front of the globe. The Cassini Division was visible all the way around the rings, with the globe of the planet faintly visible in the Cassini Division in front of the globe. The A-Ring appeared darker then the B-Ring, and the Encke Minima was visible on both ansae of the A-Ring. On the inner portion of the B-Ring shading was noted on both ansae, which was more prominent on the following or right hand side. The shading on the preceding ansae appeared to have a lighter portion between it. A ringlet or intensity minima was visible on the following ansae of the B-Ring.
Six satellites were visible near Saturn including Rhea, Dione, Tethys, Iapetus, Enceladus, and Titan. In the above sketch the two moons visible below Saturn are Dione (left) and Tethys (right). When the seeing settled down Titan appeared as a disk and had a slight reddish-orange color to it.
