This Hubble Space Telescope mosaic from Feb. 26, 2007, shows the Great Red Spot and Little Red Spot regions, with an average zonal wind field plotted over. Color is generated using a 410 nm map (blue) and 673 nm map (red), with a composite of the two in the green channel. The "GRS" is at the left near 20 degrees south, and the "LRS" with the south tropical disturbance to the north is seen at right. The south tropical disturbance is darker than other whitish clouds in its latitude band which overlaps that of the GRS.
