Highest resolution Voyager 1 color view of the Great Red Spot
Less than 8 hours before closest approach, Voyager 1 obtained a green and violet filter mosaic with its narrow angle camera (NAC) covering most of the Great Red Spot (GRS)—a total of 28 images. Here the effects of the varying illumination across the mosaic have been removed. At ~6 km/pixel, this is the highest resolution pre-Juno color data for Jupiter (all of the higher resolution Voyager images are clear filter images). Lower resolution orange, green and violet images from Voyager 1's wide angle camera (WAC) are also used to show the GRS periphery and surrounding areas. Color, contrast, and sharpness have been enhanced to better show various details.

The color in this mosaic was rather difficult to process. The WAC filters are significantly different from the corresponding NAC filters and the left/right edges are not covered by all three WAC filters. There are also some areas in the NAC mosaic where only green or violet was available (especially near the corners of the NAC area). The color is somewhat less accurate there.
