CCD photometric data for eclipses of Tethys, Dione, and Rhea are fit to model light curves that represent the geometry and radiometry of the events. Comparison of our midevent timings with modern ephemerides indicates that the predictions are typically accurate to about 300 km. We also present results from our model that allow eclipse and occultation photometry of Mimas through Phoebe to be used for precise astrometry of those satellites. ¿ American Geophysical Union 1996
