On the basis of UBV observations, the light curve of RS Oph covering more than 900 days was constructed and photometric behavior of this recurrent nova was considered. The comparison of results obtained for the 2006 outburst with that for earlier outbursts of RS Oph in 1967 and 1985 is undertaken and a good agreement between these data is found. CCD observations of RS Oph were taken in seven nights between April 21 and 29, 2007 in V and R bands. From analysis of these observations the existence of 32 min oscillations with an amplitude of ˜0^{m}.3 in R and V is suggested in addition to flickering with an amplitude of about ˜0^{m}.2 on the time-scale of minutes.
