The paper reports on the new semiautomatical meridian circle of the Pulkovo observatory. It is equipped with a scanning photoelectric micrometer and a photoelectric circle reading system. The standard errors of a single registration of a star are 0s.016 and 0″.35 in RA and declination, respectively. The limiting magnitude is 10.5m. The instrument can be used for IRS differential observations.
