The cylindrical projections of Jupiter representing Voyager 1 top and Voyager 2 are presented in this comparison.

The cylindrical projections of Jupiter, representing both Voyager 1 (top) and Voyager 2 (bottom), are presented in this comparison. The top picture extends 400 degrees longitude to 0 degrees (right edge). It is aligned with the lower image so that the longitude scale is correct for both frames. The comparison between the pictures shows the relative motions of features in Jupiter's atmosphere. It can be seen that the Great Red Spot has moved westward and the white oval features eastward during the time between the acquisition of these pictures. Regulare plume patterns are equidistant around the northern edge of the equator, while a train of small spots has moved eastward at approxiamately 80 degrees south latitude. In addition to these relative motions, significant changes are evident in the recirculation flow east of the Great Red Spot, in the disturbed region west of the Greast Red Spot, and as seen in the brightening of material spreading into the equatorial region from the more southerly latitudes.
