Astrometric positions of the Neptunian Satellite Triton are given for the oppo- sition of Neptune for the years 1996, 2003, 2005 and 2006. The 943 observed positions were obtained at the Cassegrain focus of a 156 cm reflector. In our reduction, the up-to-date catalogue of stars UCAC2 (Zacharias et al. 2004), was chosen to ensure a proper astrometric calibration. Our observed positions are compared to theoretical positions provided from JPL and IMCCE ephemerides. The observed minus calculated residuals have standard deviations of the order of 0.04”.< Réduire
