A number of investigations have interpreted the systematic redshift of many Fraunhofer lines at the supergranule boundaries as evidence for downward motion, and thus for overturning of supergranular convection cells. In the present investigation, it is shown that this interpretation is to be questioned. A description is given of the measurement and reduction of full line profiles and bisectors observed in the magnetic network and in cells. It is found that three Fe I lines studied exhibit systematic redshifts of the network wing profiles, relative to those formed in the cells, but the deep line cores are not significantly shifted. Line profile computations indicate that the redshifted wings and unshifted line cores suggest somewhat inhibited convection near the network, rather than a general downflow at supergranule cell edges.
