The shadow of the globe was visible on the rings, giving the planet a 3-D look to it. The South Temperate Belt (STeB) was visible to the north of the South Polar Region (SPR), which appeared green in color. The South Equatorial Belt appeared light brown, and in the Equatorial Zone (EZ) the Equatorial Band (EB) was visible. EZ north (EZn) was visible through the C or Crepe Ring, which appeared light gray. Shading was noted on the left or preceding ansae of the B-Ring, as well as on the following ansae. A-Ring darker then B-Ring. Cassini Division was noted all the way around the rings including in front of the globe. The Encke Minima was visible on both ansae, but was more prominent on the preceding ansae.
