December 28, 2003, 3:00 - 4:30 UT, seeing variable from 4 - 6 (fair - good) transparency 5.2.
Astro-Physics 7.1" f/9 EDT refractor on AP 800 mount. Magnification 203x - 253x with Baader binoviewer.
The South Polar Cap (SPC), South Polar Region (SPR), the South South Temperate Zone (SSTeZ), and the South South Temperate Band (SSTeB) appeared green in color.
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. A ringlet or intensity minima was visible on the following ansae of the B-Ring.
Four satellites were visible near Saturn including Rhea, Dione, Tethys, and Titan. In the above sketch the two moons visible near Saturn are Tethys (left) and Dione (right). When the seeing settled down Titan appeared as a disk and had a slight reddish-orange color to it.
