The ~15.1 years period found in the long-term UBV
photoelectric and photographic photometry of the symbiotic nova V1016 Cyg is
detected also in the 
colour index and in the UV continuum and emission
line fluxes from IUE and HUT spectra. It could be interpreted either as the
effect of recurrent enhanced mass loss episodes from the Mira type variable
companion to a hot component along its ultra-wide orbit (proposed from recent
HST observations) or the true orbital period of the inner, unresolved binary of
a triple system. The 410-day delay of the maximum of UV emission lines fluxes
with respect to the maximum of continuum was found. The pulsation period of the
Mira type variable was improved to 
days.
