This 12-footprint color mosaic of Jupiter's Great Red Spot was composed of 24 images captured through orange and violet filters by Voyager 1 on March 4,1979 at a distance of about 1.85 million km. The first image (C1635314.IMQ) was obtained at 07:08:36 and the last one (C1635400.IMQ) at 07:45:24. The resolution is roughly 18 km/pixel in the "click to enlarge" version.
