In order to study the spatial relation between 50MHz-radar echoes and visual auroral forms, a photometer observing auroral emissions at 4278Å was installed at Mizuho Station during the period from July to October, 1978. Several examples of the measurements are shown to discuss qualitative differences between the radio aurora and the optical auroras. It is shown that the correlation between optical and radio aurora intensities becomes poor in highly active aurora but is generally good for quiet aurora. Phenomena are found that the radio auroral intensities become low within auroral arcs.
