-750 observations made from 1995 June 10 to 1998 Sept. 4

Astrometric positions of four 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
have been compared with the calculated positions from GUST86. The standard
deviations are better than 0.05" for the four largest satellites and
0.08" for Miranda.
