                                 Abstract
On 1995 November 20-21, Saturn and its rings will occult GSC5249-01240
while Saturn is near its stationary point. This will result in probes of
the atmosphere at multiple latitudes and of the rings at several
longitudes. We propose to observe this event to (i) establish Saturn's
atmospheric structure in the 1-100 microbar region (inaccessible to
Voyager instruments), (ii) determine the extent of latitudinal homogeneity
in composition and temperature present near north latitudes 35-75 degrees,
and (iii) probe the ring system for features of low optical depth (with
spatial resolution better than 1 km) by taking advantage of the low
opening angle of the rings as we approach ring-plane crossing in 1995.
