Scientific paper

We present optical time-resolved spectroscopy of the old nova RR Pic. Two emission lines (Hα and He I) are present in the observed part of the spectrum and both show strong variability. Hα has been used for Doppler tomography in order to map the emission distribution in the system. The resulting map shows the emission from the disc as well as two additional emission sources on the leading and trailing side of the disc.
