Following an alert in April 1986 that an outburst of BR Lupi was in progress, high-speed photometry of this star was obtained. The outburst light curve revealed the presence of 'superhumps', indicating that BR Lup is a member of the SU UMa subclass of cataclysmic variables. Using a standard Fourier analysis, the period of the superhump was found to be 0.082 + or - 0.0002 d. The tight correlation between superhump period and orbital period found by Stolz and Schoembs (1981) made it possible to estimate the orbital period of BR Lup. It was found to be equal to 0.079 d.
