Abstract. The results of spectral monitoring of the Herbig Ae/Be star MWC 614 (HD 179218) at the 2 m telescope of ShAO have presented. It was discovered a wave like quasi-cyclic variations of radial velocities and equivalent widths with character time 10-12 days. Hα line profiles have shown an appearance and disappearance for nearly 20 days of additional emission components on the blue and red wings. On the variability of profiles of various spectral lines we have concluded that for time to time it was observed an accretion and outflow of the disc matter, what perhaps is an indicated of the presence a magnetosphere of this young star.
