Abstract
We report a CCD optical photometry of a dwarf nova AL Com in superoutb urst. Before superhumps occurred the light curve was highly variable w ith dominant periods about 40 minutes and about 80 minutes for differe nt nights. The period of observed superhumps is 82.5 minutes and seems to be stable. Its first harmonic is also detectable. The 79.3 minutes period is suspected to be a possible signature of orbital motion in t he system.
