description The absolute proper motion of the primary component of this pair is derived on the basis of all available photographic and meridian observations, spanning over 55 years. The relative trajectory is then computed from all existing differential measurements, and different criteria were used to show that the pair is optical. An ephemeris is presented for the interval 1988-2000. The proper motion for the secondary component is obtained by combining that of the primary with the relative motion, achieving a much higher precision than that allowed by the very few absolute observations of the secondary alone. Both proper motions are finally compared with other determinations. The complete version of this work will be published elsewhere.
