Abstract:
New UBV photometry of the symbiotic nova V1329 Cyg taken in 1988-97 is
presented. Long-term postoutburst UBV photoelectric, photographic and visual
observations from the AAVSO and AFOEV databases are discussed. The periodogram
analysis using the trigonometric polynomial fit with a linear trend reveals the
mean normal epoch of the minimum and the mean best fit period as JD 2446771 +/-
3 days and 956.5 day +/- 0.6 day, respectively. The amplitude of the brightness
variations is significantly higher in the U-band (1.6 mag.) than in the B,V and
pg bands (1.22 mag.). The largest slope of the mean brightness decrease is in
the U-band. The characteristics of the light-curves extremes in different bands
are tabulated. The phases of the U,B,V light-curves coincide within the error
estimates. A secondary period of 553 days and a cycle of approx. 5300 days are
suggested.
