J0720 is confirmed as a magnetic cataclysmic variable (polar) with a 1.5-hour orbit, stream-fed accretion without a disk, and unusually weak He II emission relative to H beta.

abstract
A new magnetic, eclipsing cataclysmic variable is identified as the counterpart of the X-ray source RX J0719.2+6557 detected during the ROSAT all-sky survey. The relative phasing of photometric and spectroscopic periods indicates a self-eclipsing system. Doppler tomography points to the heated surface of the secondary as a strong source of emission and of diskless accretion. Near-infrared spectroscopy revealed two unusual strong emission features originating on the heated side of the secondary.
