Ch. Veiga et Rv. Martins, NEW CCD POSITIONS OF TRITON AND A COMPARISON WITH THE THEORETICAL PREDICTIONS, Astronomy & Astrophysics. Supplement series, 131(2), 1998, pp. 291-293
Astrometric observations of Triton are given for the oppositions of Ne
ptune 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 a
nd the 0.6 m reflectors of the LNA-Brazil. The comparison with calcula
ted positions gives residuals with standard deviation of the order of
0.'' 09(1.)
