Long-term photometry of the symbiotic nova V1016 Cyg
Long-term UBVR photoelectric photometry of the symbiotic nova V1016 Cygperformed from 1971 to 2000 is presented. The archive photographicplates were used to estimate the brightness of the object during theyears 1895-1910 and 1937-1997. These data together with thepost-outburst visual observations from international databases arediscussed. The pre-outburst brightening in 1949, main nova-like outburstin 1964 and two small brightenings in 1980 and 1994 suggest a 5500-dayperiodicity of activity, interpreted as the orbital period of thebinary. In 1971, during the brightness maximum of the symbiotic nova,the outbursting white dwarf mimicked a B6 supergiant.
