ADC_Keywords: Photometry, CCD ; Clusters, open ; Photometry, Vilnius Keywords: stars: fundamental parameters - clusters: individual: M 67 Abstract: Seven-color CCD photometry in the Vilnius photometric system of 279 stars down to V=15mag in the open cluster M 67 area is obtained. 13 standard stars in the cluster are measured photoelectrically. Photometric spectral types have been determined for all the stars. The reddening of the cluster is found to be E(B-V)=0.045, the true distance modulus is 9.38mag and the age is 4x109 years.
