摘要：

UBV photoelectric photometry for 175 stars in the field of the southern open cluster NGC 2323, supplemented by DDO photometry of 5 probable giants, is presented. The analysis of the photometric data yields 109 probable members; one of them being a red giant, and 3 possible members. The reddening across the cluster is slightly variable and the mean value E(B - V) = 0.25. The apparent cluster distance modulus is 10.62, corresponding to a distance of 940 pc. The age, determined by fitting isochrones with core overshooting, turns out to be 100 +/- 20 Myr. Other fundamental cluster parameters are also determined. NGC 2323 appears not to be physically connected to the CMa OB1 association.
