Neptune
Voyager 2 image of the Great Dark spot on Neptune from 4 million km. The Great Dark Spot (GDS), at upper center, is a weather system about the size of Earth. The GDS rotates counterclockwise with a period of about 16 days. Bright clouds are visible south of the GDS. These clouds appear to be 50 to 100 km higher in altitude than the spot. The image was taken through the clear filter of the narrow angle camera. The frame is about 29,000 km on a side and north is at 1:00. (Voyager 2, 11314.46)
