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.
