Jupiter's long-lived White Ovals in True Color

September 26, 2003
Oval cloud systems of this type are often associated with chaotic cyclonic systems such as the balloon shaped vortex seen here between the well formed ovals. This system is centered near 30 degrees south planetocentric latitude and 100 degrees west longitude and rotates in a clockwise sense about its center. The oval shaped vortices in the upper half of the mosaic are two of the three long-lived White Ovals that formed to the south of the Red Spot in the 1930's and, like the Red Spot, rotate in a counterclockwise sense. The east to west dimension of the leftmost White Oval is 9000 kilometers (km). (The diameter of the Earth is 12,756 km.) The White Ovals drift in longitude relative to one another, and are presently restricting the cyclonic structure.
