Variable stars in the globular cluster M 79

We present preliminary results obtained from analysis of the V I photome- try of the globular cluster M 79. Stellar variability survey performed with the image subtraction method yielded six new pulsating stars: two of RR Lyrae type, three SX Phoenicis stars and even one W Virginis star. Using all eleven RR Lyrae stars known in the cluster we find that M 79 is Oosterhoff type II globular c luster.
