The Sun and Earth passed through Saturn's ring plane in 1995 and 1996, providing a unique opportunity to observe Saturn's faintest rings and smallest satellites. The edge-on viewing geometry also permited direct observations of the main rings' thickness, and the timing of satellite eclipses and mutual events that can be used to improve ephemerides.
Note: This page contains planning tools and information used primarily in preparation for the events in 1995 and 1996. More up-to-date observing tools are now available elsewhere.

Event Predictions
J. E. Arlot and W. Thuillot of the Bureau des Londitudes in Paris
predicted the times of events (transits, occultations and eclipses)
involving the classical satellites of Saturn.
P. D. Nicholson of Cornell University predicted the times of eclipse disappearances and reappearances for the small inner satellites. Following the May and August 1995 events, P. D. Nicholson revised the predictions of eclipse reappearance times for Prometheus, Pandora, Janus, and Epimetheus. The Prometheus event times changed rather significantly.
Saturn Viewer
This utility enables you to render a diagram showing the appearance of
Saturn, its moons and rings at any time during 1995 and 1996.
Diagrams are rendered in Postscript format.
Here are a few
examples.
Newer
observing tools
are now recommended.
Saturn Moon Tracker
This utility enables you to generate diagrams showing the motion of
Saturn's moons during 1995 and 1996. Diagrams are rendered in
Postscript format. Newer

Tucson Workshop Proceedings
A preparatory workshop for the Saturn ring plane crossing was held in
Tucson, May 26 and 27, 1994. The proceedings contain the viewgraphs
from every presentation.
