Scientific paper

Light curves of RR Pic obtained over the period 1972 - 84 show that whereas in the 1970s a strong orbital modulation of brightness was present this has been replaced in the 1980s by an irregular, shallow eclipse superimposed on a flickering background. The disappearance of the orbital modulation coincided with decline in mean brightness of the system. The cause of these structural changes, taking place 50 yr after the nova eruption, cannot be determined until a better model for the mass transfer and accretion disc structure is developed.
