Abstract
uvby − β photoelectric photometry of stars in the direction of the open clusters IC 4665, NGC 6871 and Dzim 5 is presented. From this uvby − β photometry we classified the spectral types which allowed us to determine the reddening and, hence, the distance. Membership of the stars to the cluster was determined. Our results are compared with those obtained by GAIA DR2.
