Abstract: In this study a characterisation of the physical parameters of the open cluster M67 is made by using empirical calibrations in the Ströomgren-Crawford filter system. A group of 316 stars contributed to the results. The photometric analysis leads to an extinction of Eb-y = 0:03 +- 0:03, a distance modulus V0 - Mv = 9:6 +- 0:3 (or 830 +- 60 pc), a metallicity [Fe=H] = 0:0 +- 0:3 and the age of the cluster is approximated to be log t(yr) = 9:57 +- 0:05 (or 3:72 +- 0:19 Gyr)
