Astrometric positions of the Neptunian Satellite Triton are given for the opposition of Neptune for the years 1989 to 1994. These positions where measured on 433 CCD frames obtained at the Cassegrain focus of a 1.6 m reflector. They are compared with theoretical positions calculated from Jacobson et al. (1991). The observed minus calculated residuals referred to Neptune have standard deviations of the order of 011.

Key words: planets and satellites --- satellites of Neptune --- astrometry
