Rare Low State of DO Dra, the Magnetic Dwarf Nova=Outbursting Intermediate Polar
Abstract
DO Dra is an exotic cataclysmic variable which shows properties either of the intermediate polars, or dwarf novae. It may represent a new subclass of "magnetic Dwarf Nova=outbursting intermediate polar". Very rare low luminosity state (of <R>=16.095±0.007) was detected on June 8/9, 2017. The light curve shows a double-humped shape with a phase of the orbital period, with two unequal maxima, arguing not only for an ellipticity effect, but for a bright spot as well. Totally, we have detected 3 lows states.
