The central field of NGC 7062 was observed intensively with the main goal of finding δ Scuti stars suitable for use in asteroseismological tests of stellar structure and evolution theory. BV time series photometry was obtained for this northern open cluster, which has a large population of stars inside the δ Scuti instability strip, making it a probable host of several such variables. We report findings of 15 pulsating stars, including at least 13 δ Scuti stars. Ten variables oscillate in two or more frequencies. Only one of these variables was known before, for which we detected 9 frequencies. Five probable variables are mentioned, and period analysis is given for all 20 stars.
Key words: stars: δ Scuti; evolution; oscillations / (galaxy:) open clusters and associations: individual: NGC 7062
