Positions of minor planets with the GPO at ESO – La Silla

Minor Planets were observed in February 1985 with the Grand Prisme Objectif (GPO) at ESO – La Silla. They were reduced at Uccle, Uppsala, Turin, Universidade Federal do Rio de Janeiro (Observatório do Valongo), Museu de Astronomia e Ciěncias Afins and ESO Center at Garching. Here we give those computed by the authors. The great number of positions is attained due to the experience of 9 years at La Silla and to the automatic means we have developed for more than 20 years. These means are based on more than 70 years of works at Uccle. The measurements remain very long when performed, for the sake of uniformity, by a single measurer, as in this present publication (175 positions).
