Abstract: Results are presented of the period analyses for nine Delta Scuti stars, of which six are new short-period variable stars. For some of these stars, extensive data sets covering time bases of the order of two years or more were obtained. The results from year to year are consistent with the multiperiodic solution derived from the combined data for those stars with the largest data sets. In some cases of less frequently observed stars, the results are not always compatible with one another. It is suggested that, generally, this is due to insufficient data sampling or too narrow time bases. The fact that many unevolved or slightly evolved Delta Scuti stars are multiperiodic with very small amplitudes of a couple of hundredths of a magnitude is confirmed.
