Abstract
Photographic photometry of the symbiotic nova V 1329 Cygni performed a t the Skalnate Pleso Observatory in the years 1979-1991 is presented. An observational proof of the 11d.4 orbital period increase caused by the nova-like outburst around 1966 is given. New ephemeris valid after the year 1971 is as follows: JD(min) = 2446784.862 + 963d.306 x E. Th e arguments in favour of accretion powered outburst are given.
