We report the discovery of a new cataclysmic variable DDE 32 identified withthe ROSAT X-ray source 1RXS J161935.7+524630 in Draco. The variability wasoriginally found by D. Denisenko on the digitized Palomar plates centered atthe position of X-ray source. The photometric observations by F. Martinelli atLajatico Astronomical Center in June 2015 have shown the large amplitude(nearly 2 magnitudes) variability with a period about 100.5 minutes. Using thepublicly available Catalina Sky Survey data from 2005 to 2013 we have improvedthe value of period to 0.0697944 days. Comparison of the archival CRTS datawith more recent observations from Lajatico shows the dramatic changes in thelight curve shape. Instead of a single peak present in Catalina data before2014, there were two peaks of nearly the same height during 2015. SDSS spectrumtaken in June 2009 shows prominent Helium emission lines between the brightBalmer series. He II 4686 AA line has more than 30% effective width compared toH_beta line. All those features allow us to interpret 1RXS J161935.7+524630 asa magnetic cataclysmic variable (polar) with the accretion mode changing fromone pole before 2014 to two poles in 2015.
