September 19, 1998, 2:30 - 3:05 UT, seeing 5 (0 worst, 10 best), transparency 4.5. System I Central Meridian 121.2 degrees, System II Central Meridian 71.67 degrees.
In the above sketch the preceding limb is on the left, the following limb is on the right, south is at the top, and north is at the bottom.Astro-Physics 7.1" f/9 EDT refractor on homemade Dobsonian-style mount. Magnification 184x with Baader binoviewer. An 80A filter was used to enhance the detail.
The South Polar Region appeared light brown in color. The South Temperate Zone appeared white in color.
The Great Red Spot (GRS) was light gray in color and was visible in the South Equatorial Belt (SEB). There appeared to be a small round feature at the top of the GRS.
In addition there was a dark feature along the preceding edge of the GRS as if it had a black eye. A lighter dogleg feature was visible below the GRS. The GRS transited around 1:35 UT.
The SEB seemed to be "bowed up" around the south edge of the GRS.
A Loop Festoon was visible along the North Equatorial Belt North. Also two bays were visible along the North Equatorial Belt South. The second festoon connected to the Equatorial Belt, but I was not able to see it towards the preceeding edge.
Several ovals preceded the GRS in the SEB.
The Equatorial Belt (EB) was visible in the Equatorial Zone.
The North Equatorial Belt (NEB) was reddish-brown in color.
The North Polar Region (NPR) appeared mottled and was green -blue in color.
