This false color picture of Saturn's northern hemisphere was assembled from ultraviolet, violet and green images obtained Aug. 19, 1998 by NASA's Voyager 2. The several weather patterns evident include three spots flowing westward.

This false color picture of Saturn's northern hemisphere was assembled from ultraviolet, violet and green images obtained Aug. 19 by Voyager 2 from a range of 7.1 million kilometers (4.4 million miles). The several weather patterns evident include three spots flowing westward at about 15 meters-per-second (33 mph). Although the cloud system associated with the western-most spot is part of this flow, the spot itself moves eastward at about 30 meters-per-second (65 mph). Their joint flow shows the anti-cyclonic rotation of the spot, which is about 3,000 km. (1,900 mi.) in diameter. The ribbon- like feature to the north marks a high-speed jet where wind speeds approach 150 meters-per-second (330 mph). The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
