The paper presents the results of optical photometry of the dwarf nova WX Cet, which recently went into outburst, possibly for the first time since 1963. The data, which were obtained during quiescence, show a periodic modulation of the optical brightness of WX Cet, with a period of 6.98 + or - 0.04 hours. Based on the observation of high-amplitude outbursts from a system with a 7 hour orbital period it is argued that either the secondary star is not a normal main-sequence star, or that the outbursts are not due to an accretion instability similar to that in dwarf novae.
