Abstract: Astrometric positions of the Neptunian Satellite Triton are given for the opposition 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 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 s.d. values of the order of 0.04 arcsec. The data are available in electronic form as Supplementary Material to the online version of the paper on Blackwell Synergy, at the CDS via anonymous FTP to http://cdsarc.u-strasbg.fr or via http://cdsweb.u-strasbg.fr/Abstract.html.
