This image from NASA's Voyager 2, taken Aug. 18, 1981, from a distance of 6.8 million kilometers (4.2 million miles), shows the region extending from 20 north latitude to Saturn's polar region.

This Saturn photograph has been constructed in false color from a green and a violet frame obtained Aug. 19 by Voyager 2 from a range of 7.1 million kilometers (4.4 million miles). In true color, the blue oval in the center of the image would be brown and the two spots below and to the right would be white. The convective structure below the blue oval is moving west at 20 meters-per-second (40 mph) relative to the oval. The wavelike structures in the ribbon to the north are moving eastward at 150 meters-per-second (300 mph). In this image, the smallest observable features are 130 km. (80 mi.) across. The separate green and violet frames used to construct this picture are displayed in an accompanying release (P-23916BW, S-2-13). The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
