Abstract

Evidence for variability in the star HD 349422 is presented. Low-amplitude variations seen in the Bessel B and Bessel V filters are presented for three nights on two different telescopes. A period of 0.0400 day in the B and 0.0413 day in the V filters, respectively, were determined. These periods agree within the determined uncertainty. The spectral type from the literature is given as F0. It is therefore proposed that due to the period and spectral type that HD349422 is a member of the delta Scuti family.
