  By studying young open clusters, the mechanisms important for star formation
over several Myr can be examined. For example, accretion rate as a function of
rotational velocity can be investigated. Similarly, sequential star formation
triggered by massive stars with high mass-loss rates can be studied in detail.
We identified and characterized probable members of NGC 6383, as well as
determined cluster parameters. New Stromgren uvby CCD photometry, obtained by
us, is presented. This new data, together with Johnson UBV and 2MASS data in
the NIR, was used to investigate characteristics of pre- as well as zero age
main sequence cluster members. We present Stromgren uvby CCD photometry for 272
stars in the field of NGC 6383 and derive its reddening, E(b-y)=0.21(4)mag, as
well as distance, d=1.7(3)kpc from the Sun. Several stars with NIR excess and
objects in the domain of the classical Herbig Ae/Be and T Tauri stars were
detected. Two previously known variables were identified as rapidly-rotating
PMS stars. The field population is clearly separated from the probable members
in the color-magnitude diagram. NGC 6383 is a young open cluster, with an age
of less than 4 Myr, undergoing continuous star formation. True pre-main
sequence members might be found down to absolute magnitudes of +6mag, with a
variety of rotational velocities and stellar activities.
