Abstract
We determine the positions of twelve radio sources in the frame of the Carlsberg Automatic Meridian Circle catalogue using observations based solely on CCD images. The precision per frame is 50 mas and most sources have 5 or more frames thus the accuracy of these positions is solely limited by the error in the reference stars.
Key words: astrometry
