A PHOTOMETRIC-STUDY OF THE OPEN CLUSTER HAFFNER-6

We have obtained CCD BV photometry of 665 stars in the region of the s outhern open cluster Haffner 6. The photometry of a nearby field is al so reported. This poorly studied object is shown to be of intermediate age and to have a solar metallicity. Adopting a metal content Z = 0.0 20, we found a colour excess E(B - V) = 0.43, an apparent distance mod ulus (m - M)= 13.90 and an age of about 1.0 Gyr. Consequently, we obta in a distance of about 3.4 kpc from the Sun. The main-sequence (MS) in tegrated luminosity function (ILF) is compatible with the standard Sal peter (x = 1.35) initial mass function (IMF).
