In September 1987 we have observed minor planets at La Silla, ESO, with the GPO astrometric refractor (D = 40 cm; F=400 cm). Measures and reductions were performed at the Observatório do Valongo (UFRJ) with the Ascorecord measuring machine (0,1µ) and by means of five reference stars (SAO Star Catalogue - 1950,0). By the first time, double star field were used for saving time and photographic material.Downloads
