ABSTRACT

Possible response of the ionospheric D-region to the geomagnetic storm sudden commencements at origination of the impact solar front during the Sun flares is studied experimentally using the method of partial reflection. It is determined that after a few hours since the geomagnetic storm sudden commencements electron concentration in the D-region is increased by 50...150% within tens of minutes. The hypothesis on precipitation of high-power electrons from the radiation belt is used to explain the above phenomenon; calculations of parameters of the flow of precipitating electrons are performed.
