The calculations of the circumstances for mutual phenomena of the saturnian satellites in 1995-1996

The circumstances of the mutual occultations and eclipses of the main saturnian satellites in 1995-1996 are calculated. The moments and some parameters of the phenomena are published by Emelianov et al. (1994).

The more detailed circumstances of each event as well as the seeing conditions for a given observatory may be recalculated with the program running.

As the ephemerides of the mutual events are to be precise we have to verify the program with some observational data. For testing the method and the program we used the results of 14 observations of mutual events of the saturnian satellites in 1979-1980 (Aksnes et al. 1984 ) The apparent satellite coordinates were calculated for the moments of the observations. The coordinates were taken as apparent ones from the Earth for the occultations and as apparent ones from the Sun for the eclipses. Then the differences of the coordinates in pairs of satellites were compared with the results of observations. For 13 of 14 observations the deviations of the results are not worse than 0.04 arcseconds. These deviations correspond to the errors of the moments of the event middle time being not more than 12 correspondent event duration. We believe it is reasonable for ephemerides calculations.

After we were through with the calculations the results were compared with the data published by Arlot and Thuillot (1993). Majority of the differences in the time of the event have the values being not worse than 10 deviations may be explicated by the difference between the taken theories.
