This mosaic of the Great Red Spot shows that the region has changed significantly since the Voyager 1 encounter three months ago.
Around the northern boundary a white cloud is seen, which extends to east of the region. The presence of this cloud prevents small cloud vortices from circling the spot in the manner seen in the Voyager 1 encounter. Another white oval cloud (different from the one present in this position three months ago) is seen south of the Great Red Spot. The internal structure of these spots is identical. Since they both rotate in an anticyclonic manner these observations indicate that they are meteorologically similar.
