Abstract

The paper presents the variations in the parameters of the ionosphere D-layer during x-ray flares of M and X classes on the propagation path of signals from the superluminal waves of the GQD and GBZ transmitters, as well as those adopted by the Mikhnevo State Educational Center. It is shown that, within the framework of the two-parameter Ferguson-White model, the effective reflection height of the VLF signal h’ and the gradient of increase in the electron concentration β at the leading edge of the flare are related to the x-ray energy in the range 0.05–0.4 nm.
