CCD monitoring of N Cas 1995 = V723 Cas

The observations were carried out at 38-cm reflector of the Crimean observatory with CCD ST-7 in R band. Both the primary and the secondary eclipses are seen. The eclipse ephemeris is MinI =2451441.290 +0.693326E. The local maxima of short period oscillation are seen near the light maximum. The period of oscillation may be improved with O-C method, and is equal to 0.061532 day, Max=2451432.539.


The orbital period may be confirmed with the current last two year photometry of the Nova. The following is the amplitude spectrum of the Nova. A significant peak at this position is well seen.
