We present the results of 6 years of photometric monitoring of the magnetic cataclysmic variable V2306 Cygni (formerly known as 1WGAJ1958.2+3232) obtained at collaborating observatories. Using (O-C) analysis we tried to study variability of the spin period of the white dwarf, however we cannot make a firm conclusion based on the scatter. Simultaneously, using (O-C) diagram of orbital minima, we found that the value of 0.181545(3) days better corresponds with the light curve, than do previously published orbital period values. We also found that the variability has a 2.01 day period; this variability may be interpreted as possible precession of the accretion disk in this system.
