MONITORING MWC560-V694 MONOCEROTIS IN 1990-1995 .2. PLATE SPECTRA

We present the results of the photographic spectral observations of MW C 560 carried out in the period 1990-1993. The evolution of the spectr um, the changes in the radial velocities of the different line systems , as well as the variations in the equivalent widths of the different Palmer absorption components, are given and briefly discussed. The sug gestion that the hot component of MWC 560 ejects high-velocity, highly -collimated jets along the line of sight, is in very good agreement wi th the observations. All the results, including the variations in the shapes, velocities and equivalent widths of the strong-shifted Palmer absorptions, confirm that compact companion in MWC 560 ejects matter i n two different regimes - discrete and quasi-stationary. It is suppose d that the permanent presence of a relatively weak and small-shifted P almer absorption component in the spectrum, indicates additional persi stent, not spherically symmetric matter outflow.
