Scientific paper

The absolute proper motion of the primary component of HJ 3370 AC is derived on the basis of all available photographic and meridian observations. The relative trajectory is then computed from all existing differential measurements, and the pair is shown to be optical. An ephemeris is presented for the interval 1988 - 2000. The proper motion (p.m.) of the secondary is obtained by combining that of the primary with the relative motion. Both proper motions are finally compared with other determinations.
