Abstract
V350 Peg is a delta Scuti star discovered by Hipparcos (ESA \cite{esa97}). During 35 nights between July 1997 and December 2001 some 7500 CCD V observations were acquired at the Monegrillo and Esteve Duran observatories in Spain. The new data show that this star pulsates in a close doublet of frequencies separated by 0.17 c/d (Delta f/f=3%) with similar amplitudes. More frequencies are excited but cannot be identified with certainty. The period as listed in the Hipparcos Catalogue is not confirmed. Also based on data obtained by the Hipparcos astrometry satellite.
