dc.description.abstractWe present B, V colour magnitude diagrams of the rich open cluster NGC 6603. A foreground reddening of E(B- V)f = 0.50 and an internal one of E(B- V)i = 0.29 were derived with the additional help of integrated spectra. The resulting age is 200±100Myr, and the distance is about 3.6 kpc. The surrounding field is also studied, appearing to be part of a star cloud which contains age components in the range 200 to 600 Myr or more. The cluster appears to be spatially associated with the star cloud, being part of its youngest component. The cluster and the star cloud location in the inner disk are in agreement with other studies showing an enhancement of star formation in this region.en
