Scientific paper

Observations of H-beta and H-gamma profiles in CH Cygni during 1982-84 are presented. The profiles consist of two emission peaks (VR) cut by sharp absorption. Sudden changes in the radial velocities and intensities of H-beta and H-gamma profile components as well as a drop of continuum are observed since mid-1984. The binary model of CH Cygni and possibility of occurrence of eclipses in this system are considered. Observational data are insufficient to distinguish between single and binary star models.
