Description:
Astrometric positions of the five largest satellites are given for the
oppositions of Uranus for the years 1989 to 1994. These positions were
measured on 368 CCD frames obtained at the Cassegrain focus of a 1.6-m
reflector. They are compared with the theoretically calculated
positions from GUST86 (Laskar & Jacobson 1987). The observed minus
calculated residuals referred to Oberon have standard deviations of
the order of 0.05" for the three greatest Uranian satellites and 0.07"
for Miranda. These residuals are comparable to the best available in
the literature.
