A review of our investigations of CH Cygni in its inactive state during the period 1987-1989 has been given. Optical spectra reveal the development of physical conditions in the photosphere of the cool component as well as changes in the accretion complex around the hot component. The apparently quiescent star was actually evolving in trainsition between adjacent outbursts.
