The purpose of our work is to get the solutions of the inverse VLF problems during the powerful solar proton precipitations (SPP), which continued several days and began on September 29, 1989, 1200 UT [1, 2], and October 19, 1989, 1300 UT [1]. We compared quantitatively the daily variations of the solar proton fluxes with the dynamics of the reflection properties of the bottom edge of the ionosphere. For this realization, we used the variations of VLF signals for a completely auroral VLF propagation path Aldra (Northern Norway) –Apatity (Kola Peninsula).
