Our observations with the 1.5-m Russian-Turkish Telescope (RTT 150) 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 (V = 17.0-21.(m)5). Due to the favorable geometry (the orbital inclination is close to 90 degrees), the light Curve exhibits eclipses of the white dwarf by the secondary component and eclipses of the hot spot by the white dwarf itself.
