This catalog contains optical positions of 221 radio stars observed with the Bordeaux automatic meridian circle. The observations were strictly differential, a convenient number of FK5 stars being used each night to calculate the instrumental parameters. The mean positions were corrected for chromatic refraction and also for photocenter effect in the case of duplicity. The asymptotic accuracy is expected to be about 0.05" for the Northern stars with a number of observations greater than 25. Some positions have been published previously, and the improved positions given here supersede earlier published data.
