                                 Abstract
This proposal is for far-UV imaging of Saturn's aurora and airglow
emissions, primarily from H Ly alpha (1216 A) and the H2 Lyman and Werner
bands (900-1650 A). We will determine the extent and spatial distribution
of the UV auroral oval emissions in the northern polar region, believed to
be at high magnetic latitudes. With the north pole tilted toward the
Earth, we can image the entire northern auroral oval. The airglow
emissions will appear brightest near the limb, where we can obtain an
altitude resolution of 760 km/WF pixel. The changes in the airglow near
the ring shadow region will be particularly interesting in determining the
source of the known enhanced electron-excited emissions from the outer
planets. These observations constitute the first phase on this WFPC2 GTO
program on Saturn's upper atmosphere and rings.
