Using Alard's (2000) image-subtraction method, we recently discovered a number of new variables in this cluster, pointing to an unusual Oosterhoff-intermediate classification (Corwin et al. 2003). The present study also uses image subtraction with the data reported on in our previous analysis. This time, however, the image subtraction threshold was substantially reduced. This produced thousands of false identifications, but, in addition to the previoulsy known variables, we found four new variables, all very close to the cluster core. Here we present periods and light curves for the four new variables.
