Abstract:
CCD photometry observations of young open cluster NGC 1931 in UBVRI passbands have been made down to 20.5 mag. The reddening across the cluster is found to be variable. The reddening varies from E(B – V)min = 0.55 mag to E(B – V)max = 1.00 mag. A distance of 2.17 kpc, an age of ~10⁷ yr and luminosity function for the cluster have also been derived. The luminosity function has been compared with the luminosity function of other young clusters.
