Abstract: The new CCD observations of recurrent nova RS Oph were taken in April 2008 in continuation of our study of short-term variability of this star. They were carried out with 50 cm and 60 cm telescopes of Sternberg Astronomical Institute in Crimea. The analysis of all our data obtained in 2007 and 2008 reveals a periodic oscillations with different periods on the time scale of dozens of minutes and flickering with an amplitude of about ~ 0m.2 on the time scale of minutes. The consideration properties of detected brightness variations shows that they could be interpret as a quasi-periodic oscillations.
