The recurrent novae consist of two groups of variables: long period binaries (hot WD + giant) and short period binaries (WD + main sequence star). The first ones are simular to symbiotic stars, the secon ones - to classical novae. The recurrent nova RS Oph with the orbital period 455.72 days is a member of long period binaries group. Here we present CCD observations of RS Oph carried out in April, August and September 2007 with the help of three telescopes in Crimea aimed to study photometric variability of this star. The flickering and oscillations with period about 32 min are detected in the light curves of RS Oph.
