| Abstract: | In the course of our search for the optical identifications of ROSAT X-ray sources, we have found a highly variable object
with a very unusual behavior on long time scales, rare color indices, and a high X-ray-to-optical flux ratio. We present the
archival light curve from the Catalina Sky Survey, optical spectroscopy from RTT150, and time-resolved photometry from the
Astrotel-Caucasus telescope. The object appears to be a magnetic cataclysmic variable (a polar) with an orbital period P = 3.20 h. |
