Scientific paper
Optical positions of 21 radio sources are presented. The positions were determined using reference stars from the meridian circle program of Brorfelde. The internal accuracy of the positions is of the order of 0.12 arcsec, while comparisons of these positions with optical positions and accurate radio positions available in the literature show rms deviations between the various catalogs of about 0.2 arcsec.
