We report spectrophotometric observation of a new cataclysmic variable star J 05.23, discovered as a byproduct of the Calan-Tololo Survey of quasars and Seyfert galaxies. From the ESO Quick Blue Chart we estimated a B magnitude of 17.5. The spectrum between 3200 and 6500 angstroms shows strong emission in the He I lambda-5876 angstroms, HBeta, HGamma and Hdelta lines, with FWHM of 2200 km s-1. Several lines, particularly He I lambda-5876 angstroms and HBeta exhibit double peaked profiles, with a separation of 1000 km s-1.
