Scientific paper

Using CCD observations, and the wavelet analysis method of Coupinot et al. (1991) to reduce the images, a survey of globular clusters (GCs) was performed. As a result, 23 already known GCs were confirmed and 12 new reliable candidates were discovered. The new GCs have generally small cores and are fainter than those previously known. They make it possible to fill the faint part of the luminosity distribution of M31 GCs, which is now more comparable to that for GCs of the Milky Way. Being similar in magnitude and core radius to GCs classified as post-core collapse clusters in the Milky Way, these GCs appear to solve the problem of the 'missing GCs' in the bulge of M31.
