AbstractThe correlation between AE, Ap and Dst indices, on the one hand, and nighttime critical frequencies, on the other, in northern midlatitudes in investigated. The correlation is closest for the Dst-index. A possible mechanism involving the effect of ring currents on the electron density in the mid-latitude F-region is mentioned.
