The Carlsberg Automatic Meridian Circle (CAMC) has been operating on the island of La Palma since 1984. Since that time it has made more than 500,000 observations of stars and minor planets. Observation are made by accumulating the output from a series of scans by a pair of 4″ wide slits which oscillate back and forwards across the star as it traverses the meridian (Helmer et al. 1991). The error of a single determination of a star position is 0″.14 in RA and Dec and 0.05 in V magnitude. For 20 observations, the errors of a mean position are reduced to about 0″.05.
