On the base of the radial-curve solution we have determined the elements of the orbit and determined the period P = 2.365102 days. We have disentangled the spectra of the two components of the system and derived the basic parameters of both components. We have shown that moving features in the Si iii line profiles seen in the spectra of the primary can be interpreted in the frame of the assumption of the rotation of local spot-like inhomogeneities on the stellar surface. We have also found that the lines in the spectrum of the secondary show another type of variability.
