ADC_Keywords: Clusters, globular ; Colors ; Photometry Mission_Name: HST Keywords: galaxies: star clusters Abstract: We have analyzed HST/WFPC2 images of NGC 3597 and find ≃700 compact objects surrounding the galaxy with an average (B-R)0 ≃0.6. We propose that the majority of these objects are young globular clusters. They have a spread in colors that is consistent with that expected for a population of young clusters with a common age and spread induced by photometric errors and reddening within NGC 3597. Description: NGC 3597 was observed with the WFPC2 on 1997 May 16 in the F450W and F702W filters. In the F450W filter, we took four exposures of 1300 s each. In the F702W filter, exposure times were 1100 and 3 1300 s. The F450W and F702W filters are comparable to broadband B and R filters.
