The solar Lyman-alpha emission, the Mg II core-to-wing ratio (R) the 10.7-cm radio flux, F(10.7) and the 1-8-A X-rays are compared during high solar cycle 21 activity from 1981-83. Daily variations of the Mg II and Lyman-alpha UV lines are highly correlated. There is moderate linear correlation between these lines and F(10.7) and poor linear correlation with 1-8-A X-rays. Power-spectral analysis indicates that all four fluxes have 27-day periodicities due to solar rotation while R and Lyman-alpha have noticeable 13-day periods. F(10.7) moderately represents the 27-day solar UV variations and represents to a lesser degree variations shorter than or longer than rotation variations.
