In September 1977, we have observed Minor Planets at Rio de Janeiro, most of them indicated as to be observed (signed X, XX or + in Ephemerides Minor Planets from ITA or required by Program of Leningrad) . The instrument Astrographic Camera (f = 170cm, Φ 25cm) was used. By clear sky, magnitude 13.5 to 14 could be attained. Measures and reductions were performed at the Observatório do Valongo with the Ascorecord measuring machine (0,1 µ ) and by means of five reference stars (SAO catalogue) on the Burroughs B6700 NCE-UFRJ computer.
