This paper describes the results of an HST WFPC2 search for star clusters inactive star-formation regions of M31. Nine of the clusters were previouslycataloged and 77 are new. Our 23 fields cover key areas of the galaxy's recentstar formation activity. We provide a catalog of positions and integratedmagnitudes in four colors, taken with the 336W, 439W, 555W and 814W filterswith the Hubble Space Telescope. A future paper will discuss the results ofstellar photometry in some of the clusters in six colors, including twoadditional uv colors (Bianchi et al. 2010). The integrated magnitudes andcolors of the clusters show a range of characteristics, but the mean color isbluer than for previous surveys, reflecting the concentration of our sample onactive star forming regions. Absolute magnitudes range from M555 = -10.3 to -3.5. The observed luminosity function shows a nearly Gaussian distribution witha peak value at M555 = -5.4 and a shoulder of unusually-bright clusters. Welook in detail at two of these unusually bright examples, cluster 45 (C410) andcluster 10 (BH05). C410 lies at the core of a bright HII region. Its absolutemagnitude is M555 = -10.3. BH05 is a similar object, with an absolute magnitudeof M555 = -8.9. These two clusters are among the most luminous young clustersin M31.
