Abstract: We have determined spectroscopic orbits based on the radial velocities for the giant and the hot companion from the M-giant absorption lines and from the broad wings of HI emission lines, respectively. A set of blue absorption lines is present in all our spectra except those obtained in April 2006 which cannot be associated with either binary component. Spectral variations related to the 2006 outburst are also discussed.
