February 25, 2002, 0:20 - 0:35 UT, seeing 4 (fair), transparency 2. System I Central Meridian 335.5°, System II Central Meridian : 78.4°.
Astro-Physics 5.1" f/8.35 EDF refractor on homemade Dobsonian-style mount. Magnification 168x with Baader binoviewer.
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). The SEB appeared to be bisected by a light colored rift preceding the Red Spot Hollow/Great Red Spot (RSH/GRS), and the GRS itself appeared pale pink in color. The GRS appeared to transit at approximately 0:28 UT giving it a System II Central Meridian of 77.2°.
Just above and preceding the GRS along the STB north was oval BA. There appeared to be a number of white ovals following the RSH/GRS. Europa appeared near the preceding limb of the globe along the SEB north. The shadow of Europa appeared along the SEB north below the ovals following the RSH/GRS. Europa egressed at approximately 0:36 UT.
In the Equatorial Zone (EZ) a loop festoon or garland was visible along the North Equatorial Belt (NEB) south. One red bar or rod was visible in the NEB, preceding a rift in the NEB which extended from the EZ to the North Tropical Zone (NTropZ).
The North Temperate Belt was prominent, and along the southern portion of the North Polar Region (NPR) a large dark condensation was noted.
Callisto began to disappear into Jupiter's shadow at approximately 0:17 UT, but was still faintly visible until approximately 0:25 UT. Callisto, along with Ganymede and a star below Jupiter, formed a triangular shape.
