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 0.05" for the four largest satellites and
0.08" for Miranda.
