We present BVRI CCD photometry of 3149 stars in the SMC populous clust
er Kron 3. Radial dependence of the horizontal branch morphology has b
een revealed. Contrary to Rich et al. (1984, ApJ, 286,517), we conclud
e that the cluster radius is about r=6'. We estimate the cluster metal
licity as [Fe/H]=-1.26 and its apparent distance modulus as (m-M)=18(m
).75. Our estimate of the cluster age, based on fitting isochrones of
VandenBerg & Bell (1985, ApJs, 58, 561) to our V-(B-V) and V-(V-R) dia
grams, is about 10 Gyr, the lower limit being 8 Gyr; this value is gre
ater than those derived earlier, presumably partially due to the dista
nce modulus values used by earlier investigators being too large. Our
age estimate is not far from the upper value from Rich et al. (C) 1996
American Astronomical Society.
