March 16, 2003, 2:30 - 2:50 UT, seeing 5-6, 7 - 8 (good - very good), transparency 3. Central meridian longitudes: System I: 175.8° System II: 228.1°. Astro-Physics 7.1" f/9 EDT refractor on homemade Dobsonian-style mount. Magnification 275 - 306x with Baader binoviewer. Filters used: none, Sirius Optics PC1. In the southern portion of the globe the following zones and belts were visible: the South Polar Region (SPR), the South Temperate Zone (STZ), the South Temperate Belt (STB), the South Tropical Zone (STropZ), and the South Equatorial Belt (SEB). There appeared to be a light colored rift in the SEB near the SEB south. This rift connected to the STropZ. An elongated condensation was visible along the SEB north. In the Equatorial Zone (EZ) several large ovals were visible, the central one having a darker edge along its northern side. The EZ appeared veiled, shaded or dusky. The Equatorial Band (EB) had a very irregular shape to it. The North Equatorial Belt (NEB) appeared to have several rods or bars along its northern edge, as well as a couple of bays and one white oval. The North Temperate Belt was not visible having recently faded to invisibility, although it is beginning to show faintly in images of the planet. The North North Temperate Belt (NNTB) has faded as well, but one dark segment was visible at the latitude of the NNTB. The North Polar Region (NPR) appeared mottled and had a pronounced "cap" to it. Limb darkening was noticeable on both sides of the globe. The moons appeared as disks, with Callisto appearing light gray in color, Io white/light yellow/light orange, Europa white, and Ganymede light-medium yellow. |
