The proposal is made that the 10.7-cm flux from the sun, generally regarded as a good index of the solar extreme ultraviolet radiation EUV, does not vary the same as the EUV, especially over a solar cycle. Data are given that lead to the conclusion that the flux and the EUV should be correlated in some degree, since many features of the sun vary with the solar cycle. With regard to the radio waves represented by the flux and optical manifestations in the EUV region, however, no exact casual relation between these groups of phenomena has been advanced.
