Scientific paper

The V and R light curves for 30 RR Lyrae stars in M15 were used to calculate their physical parameters. The Blazhko effect, previously reported in V12, was not detected. The determined values of the iron content and distance of the cluster are: [Fe/H] = 0.24 and d = 8.67 metallicity and metallicity - effective temperature, valid for globular clusters.
