Scientific paper

UBVI CCD photometry of open cluster NGC 2324 is presented. C-M diagrams of this cluster show well-defined main sequence with a red giant clump centered at B-V=1.05, V=13.45. We derived the major cluster characteristics; E(B-V)=0.17+-0.12 from color-color diagram and mean color of red giant clump stars, (m-M)_0=13.1+-0.1 from zero age main sequence fitting, and [Fe/H] ~ -0.32 from comparison the theoretical model developed by Bertelli et al. (1994) to the observed C-M diagrams. We estimate the age of NGC 2324 to be logt ~ 8.8 by applying isochrone fitting and morphological age index method.
