Abstract: We present a spectroscopic analysis of the delta Scuti star rho Pup on the basis of high resolution data spread over 4 consecutive nights. Despite the clearly sinusoidal shape of the radial-velocity curves, cycle-to-cycle variations are observed. A frequency analysis points towards the already known frequency nu(0) = 7.098168 c.d(-1) assigned to a radial mode and towards two possible secondary non-radial oscillations at nu(1) = 7.8 c.d(-1) and nu(2) = 6.3 c.d(-1) of much smaller amplitude.
