Scientific paper

The results are given of spectrophotometric observations of the symbiotic star V 1016 Cyg in the band 3300-7500 A with delta gamma = 50 A in 1980-1985. Against the background of a gradual increase in the degree to which the emission spectrum of the gaseous shell is excited, it was discovered in 1984 that a compact gas-dust formation was emerging, with a high degree of self-absoption in the lines of the Balmer series for hydrogen, and effectively screening the hard Lc radiation of the hot component. Towards the middle of 1985 this new formation had already dissipated for the most part. Estimates from the observational data are given for the physical parameters of 1016 Cyg.
