The positions in right ascension and declination of 50 radio stars observed with the Repsold Meridian Circle at Cerro Calan, National Observatory, are presented. The positions of these radio stars are given in the FK5 System, for the epoch of the observation and the equinox J2000.0. The mean internal error of a star position is ±0.010s and ±0.10", in right ascension and declination, respectively. The residuals in right ascension and declination of 24 FK5 radio stars and a comparison of the results of 31 radio stars observed at San Fernando and 22 stars observed at La Palma, Spain, are presented.
