Photoelectric uvby photometry has been obtained for about 30 F-type stars in each of the open clusters M67 and NGC3680. For some of the stars the H-beta index was also observed. The photometry was carried out with the Danish 1.5 m telescope at La Silla by the aid of a four-channel uvby photometer and a two channel H-beta photometer.
