Scientific paper

On six occasions in 1985 and 1986 strong, resolved components of forbidden O III lines were found at velocity displacements of + or - 150 to 200 km/s from the central component whose velocity is similar to that of many lines of various degrees of ionization. A similar component was probably present in 1982. Extensive velocity data are presented and H-alpha profiles at five phases of the 964-day cycle are displayed. The data are discussed in terms of a bipolar flow either in the plane of the orbit or perpendicular to the orbital plane of a symbiotic binary system.
