Abstract: Results of photometric and spectroscopic investigations of the recently discovered cataclysmic variable star 1RXS J180834.7+101041 are presented. Emission spectra of the system show broad double peaked hydrogen and helium emission lines. Doppler maps for the hydrogen lines demonstrate strongly non-uniform emissivity distribution in the disc, similar to that found in IP Peg. It means that the system is a new cataclysmic variable with a spiral density wave in the disc. Masses of the components ($M_\mathrm{WD}=0.8\pm0.22 \mathrm M_\odot$ and $M_\mathrm{RD}=0.14\pm0.02 \mathrm M_\odot$), and the orbit inclination ($i=78^\circ\pm1.5^\circ$) were estimated using the various well-known relations for the cataclysmic variables.

Keywords: cataclysmic variables, eclipsing stars, 1RXS J180834.7+101041.
