Medium resolution spectra of the dwarf nova BV Pup obtained during an outburst confirm the relatively long orbital period (P ~ 6.4 h). The emission lines reveal rather structured profiles that are produced in the disc and in the stream. Doppler tomography shows clear bright spot regions in Hβ and HeII 4686 Å emission line flux. Dynamical solutions for the system parameters are only found if the external radius of the accretion disc is close to the circularisation radius.
