Abstract. Almost all the stars in a circular area with a radius of about 12 min. of arc, were measured photometrically down to V="13".80 mag., using plates obtained with the Uppsala Schmidt telescope Mt. Stromlo and the Schmidt telescope at Lembang. The photographic measurement generally confirm Enggen’s remarkable result that NGC 6383 is a very young cluster, similar to NGC 2264. Groups stars lying on different parts of the colour magnitude diagram NGC 6383, are discussed in connection with Herbig’s idea about non-coevalness of stars in stellar cluster.
