Abstract:

Astrometric positions of the five largest Uranian satellites from 750 CCD frames taken at the oppositions of 1995 through 1998 are presented. The images were obtained over 35 nights. Observed positions are compared with the calculated positions from GUST86. The standard deviations are better than $0\hbox{$.\!\!^{\prime\prime}$}05$ for the four largest satellites and $0\hbox{$.\!\!^{\prime\prime}$}08$ for Miranda.

Key words: planets and satellites -- Uranian system -- CCD astrometry
