VI CCD photometry in NGC 6631

We present VI CCD photometric observations of about 5500 stars up to a limiting magnitude of V~20 in an area of ~16'x16' around the cluster NGC 6631. The cluster parameters determined for the first time by fitting the theoretical isochrones in the V, (V-I) diagram of the cluster stars are E(V-I)=0.60+/-0.05mag, distance=2.6+/-0.5kpc, age=400+/-100Myr and metallicity, Z=0.05. The cluster diameter determined from the radial density profile is 4.8+-0.5pc. The mass function of the cluster has a slope of 2.1+/-05.
