Abstract The results of spectral and photometric study of the recurrent Nova RS Ophiuchus are presented and discussed. Observations were carried out in 2009–2016. During these eight years the fluxes of HI and FeII emission lines have slightly decreased by a factor of 3 - 4. H α and H β exhibit double-peaked profiles with a central absorption. The ratio of the blue and red peaks intensities( V/R ) varies from 0.3 to 1.0 for H β and from 0.4 to 0.7 for H α . Possible correlations between changes of the ratio and other spectral parameters were investigated. Dependence of V/R on the radial velocity of absorbtion component is found out.
