Abstract: We present the results of high-resolution spectroscopic observations of the pre-main-sequence (PMS) Herbig Be star HD200775 obtained between August 1994 and December 1999. The behaviour of H , H and He i before, during, and after the last high-activity event of the object in 1997 is studied. Acomplex picture of the circumstellar evolution in this period is discussed. It is concluded that the results of observations can be interpreted in the framework of a model with a variable stellar wind originating from the star. We emphasize the importance of coordinated high-resolution spectroscopic observations for further understanding the star’s behaviour.
