Abstract:
Photoelectric UBV magnitudes of 50 stars in the field of M39 have been obtained for most of which previous photoelectric data were not available. These include 36 new members given by Platais (1984). The reddening for the cluster has been found to be 0.03 mag. A distance of 300 pc has been estimated for the cluster. The age of the cluster lies between 2.0x10⁸ and 4.0x10⁸ yr.
