Scientific paper

Based on observations obtained with the uvby photometer on the 50-cm ESO telescope in Chile, the A6V star HD 126859 is found to be a normal main sequence Delta Scuti star with low amplitude pulsation. A primary period of 0.0528489 d with an associated full light range of 0.015 m in V is derived, and the secondary period being 0.059694, the period ratio of 0.89 suggests either nonradial or high overtone pulsation. No evidence for a change of the periods in time is found.
