Astrometric observations of Triton are given for the
oppositions of
Neptune on 1995, 1996 and two nights in 1997. In this period, 759
frames were obtained during 35 nights at the Cassegrain focus of
the 1.6 m and the 0.6 m reflectors of the LNA-Brazil. The
comparison with calculated positions gives residuals with standard
deviation of the order of 
.
