We have looked for dwarf novae eruptions in the cluster cores of both 47 Tuc and NGC 6397. The cluster cores were imaged in parallel when the deep white dwarf field was imaged. We have also included archival images of the cluster cores taken with WFPC2, ACS and WFC3. We describe here all the data, our methodology and the total number of dwarf novae discovered. We explore what the number of dwarf novae implies about the total population in the cluster core.
