Scientific paper

We present photometric observations of the short-period dwarf nova TV Corvi during a superoutburst in 1994 June. Our high-speed photometric observations cover six nights and show well-defined superhumps. Using our measured superhump period, we confirm TV Crv as a short-period dwarf nova, with a likely orbital period of 1.50h. Assuming that the cause of the superhumps is a 3:1 tidal resonance, theory allows a mass ratio of q=0.22 to be predicted. This in turn provides mass estimates for the two components of M_1=0.52 M_ and M_2=0.12 M_. Assigning TV Crv a probable absolute magnitude based on current work on faint, large outburst amplitude dwarf novae, we find a distance of 350 pc.
