The Enigmatic Behaviour of the Old Nova RR Pic
We report preliminary results of an observing run at the 1—m telescope
at CTIO during which we followed RR Pic over several nights in February
2005. The resulting light curves show no sign of an eclipse. Apart from
the 3.48 h period, which is usually interpreted as the orbital one, we
find an additional period at P=3.78 h, which we interpret as the
superhump period of the system. We furthermore present high resolution
Doppler maps in Hα, Hβ and He II, which we derived from
observations at the NTT, La Silla in February 2004. They show strong
variations in the emission distribution from one day to the next. While
Hα and Hβ emission clearly show the accretion disc with some
additional isolated sources, the He II emission is confined to an
elongated region at low velocities.
