Description
The main astrophysical parameters of 24 previously unstudied open clusters of Berkeley catalogue are presented here. JHK near-infrared (Two Micron All Sky Survey, Cat. II/246) photometry and the proper motions astrometry of Naval Observatory Merged Astrometric Dataset (NOMAD, Cat. I/297) are used. The clusters' centres, angular diameters, ages, distances and colour excesses for these clusters are estimated for the first time.
