The multiple frequencies of the delta Scuti star V350 Peg
V350 Peg is a delta Scuti star discovered by Hipparcos (ESA\cite{esa97}). During 35 nights between July 1997 and December 2001 some7500 CCD V observations were acquired at the Monegrillo and Esteve Duranobservatories in Spain. The new data show that this star pulsates in aclose doublet of frequencies separated by 0.17 c/d (Delta f/f=3%) withsimilar amplitudes. More frequencies are excited but cannot beidentified with certainty. The period as listed in the HipparcosCatalogue is not confirmed. Also based on data obtained by the Hipparcosastrometry satellite.

We publish 1879 radial velocities of stars distributed in 105 fields of4^{\circ} \times 4^{\circ}. We continue the PPO series \cite[(Fehrenbachet al. 1987;]{Feh87} \cite[Duflot et al. 1990, 1992 and 1995),]{Du90}using the Fehrenbach objective prism method.
