Scientific paper

Deep UBVRI-CCD Johnson photometry for 123 stars in the densest region of IC 348 open cluster were obtained during three observational runs (October 1992, December 1993 and December 1994) at Calar Alto (Almeria, Spain). Colour-colour and colour-magnitude diagrams allowed us to classify 114 stars as members of the cluster and to confirm a large presence of pre-main sequence stars. Individual reddening values were computed for the brightest members. The structure and sub-clustering were discussed and a new sub-cluster was identified. On the assumption that all the stars in the cluster were born at the same time, an age of 3-7x10^6^yr was derived from PMS evolutionary models for low mass stars.
