CICLOPS: Cassini Imaging Central Laboratory for OPerationS

This image of Neptune was taken through the clear filter of the narrow-angle camera on July 16 when the Voyager 2 spacecraft was at a range of 57,000,000 kilometers (35 million miles).

The image was processed by computer to show the newly resolved dark oval feature embedded in the middle of the dusky southern collar. The large dark spot nearer the equator is also prominent on the left edge of the disk. The new small dark spot rotates faster than the large dark spot indicating that the winds on Neptune have different velocities at different latitudes as is the case for Jupiter, Saturn and Uranus.

The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
