South is at the top of this sketch, following is on the right hand side, north is at the bottom of the sketch, and preceding is on the left hand side.
The South Polar Region appeared light brown in color. The South South Temperate Zone (SSTZ), South South Temperate Belt (SSTB), South Temperate Zone (STZ), South Temperate Belt (STB), and white oval BC were visible along a discontinuous South Temperate Belt south near the following limb.
The South Equatorial Belt (SEB) appeared light brown in color. Along the SEB south (SEBs) the Great Red Spot (GRS) was visible which was gray in color. A rift preceded the GRS and extended to the preceding limb of the planet. An additional rift was visible below the GRS, and two white ovals followed the GRS.
There appeared to be a large patch or dusky white area in the Equatorial Zone that connected to the SEBn and NEBs.
The North Equatorial Belt appeared light brown in color. The North Temperate Belt south (NTBs), North Temperate Belt north (NTBn), and North Temperate Zone (NTZ) were prominent, and three dark spots were noted in the NTZ. Two more dark spots or condensations were located in the North North Temperate Zone (NNTZ), and the North North Temperate Belt (NNTB) and North North North Temperate Zone was prominent as well. The North Polar Region appeared light green in color.
