During an superoutburt of IX Dra, an extra period of ~96 min is detected that may correspond to the orbital period of the binary system. A later outburst showed that this period had decreased a little, thus allowing to constrain the mass of the secondary to around 30 earth masses.

IX Dra is a frequently outbursting dwarf nova probably composed of a white dwarf and a low mass companion of brown-dwarf-like mass.
