The Great Dark Spot on Neptune, green filter image from 3.9 million km

Neptune
Voyager 2 green filter image of Neptune showing the Great Dark Spot (GDS). The GDS is an anticyclonic weather system roughly the size of Earth. Centered at 20 S, the system rotates counterclockwise with a 16 day period. The bright clouds are about 100 km higher in altitude than the GDS. The image was taken from about 4 million km and measures approximately 29,000 km on a side. Neptune is 49,500 km in diameter and north is at 1:00. (Voyager 2, 11314.35)
