Next Year 1995 will be unique for the study of the saturnian satellite dynamics. The mutual occultations and eclipses of the main saturnian satellites occur each fourteen years. The immediate future such period will be from April 1995 to February 1996. Photometric observations of those rare phenomena provide the precision of the satellite positions of about 0.01" as the modern photographic observations give the satellite positions with an accuracy not better than 0.1".
Photometric observations of phenomena in question allow to improve the satellite motion theory and to determine the satellite diameter. The precision of those data is to be comparable with the precision of the data obtained by spacecraft.
For any given observatory only a part of these events can be observed. On the other hand the observations made on some observatories may be unique.
