摘要：
uvby - beta photoelectric photometry of sixty-five stars in the direction of the open cluster NGC 1528 is presented. From the uvby - beta photometry of the cluster we classified the spectral types of the stars which allowed us to determine the reddening (E(b-y) of 0.196 +/- 0.054) and hence, their distance, in parsecs, of (954 +/- 154). We determined membership of the stars to the cluster and the age (Log age equal 8.04) of the cluster. A metallicity [Fe/H] of -0.31 +/- 0.08 was calculated.
