The contrast levels appear to be smoother than prvious observations.

Seeing was rather variable and there were some patchy clouds occasionally obscuring the planet. Still, there were a number of interesting things which seemed to be present on the disk:
Illuminated Disk: The first thing that caught my attention was a bright oval/wedge shaped object, apparently in the bright limb band and extending through into the darker disk shadings (this effect was present in the W#47 and the W#21). Shading on the disk a little more subtle than before. IN the W#47 the shading seemes to appear darker and coarser while in the W#21 it is finer.
Unilluminated Disk: Not seen.
Bright Limb Band: Both visible and complete.
Terminator: Geometrically Regular- dark terminator shading present.
Cusp Caps: Both cusp caps present and about equal brightness- SPC still larger.
Cusp Collars: Both present but northern collar brighter?
