Abstract:Our observations with the 1.5-m Russian-Turkish Telescope (RTT150) in October 2005 as part of the program for identifying ROSAT X-ray sources revealed deep eclipses in the cataclysmic variable 1RXS J020929.0+283243 in Triangulum. We determined the orbital period of the binary (96.26 min) and the range of its magnitude variations ></img>                                </span>                              </span>. Due to the favorable geometry (the orbital inclination is close to 90°), the light curve exhibits eclipses of the white dwarf by the secondary component and eclipses of the hot spot by the white dwarf itself.</td>
