January 23, 2002, 1:30 - 1:45 UT, seeing 5 - 6 (good), transparency 2. System I Central Meridian 207.1, System II Central Meridian : 277.2.

Astro-Physics 5.1" f/8.35 EDF refractor on homemade Dobsonian-style mount. Magnification 231x with Baader binoviewer.

In the southern portion of the globe the following zones and belts were visible: the South Polar Region (SPR), the South South Temperate Zone (SSTZ), the South South Temperate Belt (SSTB), the South Temperate Zone (STZ), the South Temperate Belt (STB), the South Tropical Zone (STropZ), and the South Equatorial Belt (SEB). The STB appeared wider near the following limb.

The SEB appeared to be bisected by a light colored rift. A faint Equatorial Band (EB) was visible in Equatorial Zone (EZ), and one loop festoon extended from the North Equatorial Belt (NEB) south and connected to the EB. Two red bars or rods were visible in the NEB, the first one near the preceding limb, while the second one was near the following limb, and was followed by a small white oval. There appeared to be a rift along the NEB north.

The North Temperate Belt was prominent, and was noticeably thicker from the preceding limb across to near the following limb. In the southern portion of the North Polar Region (NPR) a large diffuse dark condensation was noted. The NPR appeared mottled. The northern portion of the NPR appeared green in color.

The Jovian moons appeared as disks and had subtle but noticeable differences in color.
