Abstract:
    In this work we present the detection of 33 star clusters and 51
    candidates in one field of the near by galaxy M 33. This study is
    based on WFC/ACS images available from the HST archive. Thanks to the
    high resolving power, we were able to confirm that two candidates
    previously indicated by Christian & Schommer (1982ApJS...49..405C) are
    indeed star clusters. We list the main properties for the star
    clusters (and candidates), along with some peculiar objects, such as
    background galaxies and possible HII regions.
