11-Year solar cycle extreme ultraviolet and soft X-ray variations according to the ionospheric E-region data and results of direct measurements

A new solar-ionospheric index for representing both the relative variations of the short-wave ultraviolet (EUV) and soft X-ray emissions of the Sun is developed on the basis of investigating the ionospheric E-region as a global natural detector of solar radiation. (Values of EUV-variation for almost...
