Nova Cas 1995 probably finished its long supersoft X-ray source phase. This SSS phase was accompanied with periodic (0.6932672d) brightness variation interpreted as orbital wave. The amplitude of these variations increased until 2005. It reached 2.0 mag in the B band. Then it was decreasing slowly. The abrupt change came in 2015. Goranskij et al. reported amplitude only 0.3 mag (2015ATel.7985….1G). I observed V723 Cas regularly since 2010 with 1 meter VNT telescope. Unfortunately in 2015 Goranskij was the first to observe the target.
