Abstract:
   Positions of Uranian satellites from 333 photographic plates obtained at 
   the Cassegrain focus of a 1.6 m reflector are given for the oppositions of 
   1983 through 1988. These positions were reduced using photometric methods 
   and compared with those calculated theoretically calculated from GUST86. 
   The observed minus calculated residuals referred to Oberon, have standard 
   deviations of the order of 0".04 for the four greatest Uranian satellites 
   and 0".09 for Miranda. These residuals for the four satellites are better 
   than the most precise found in the literature.
