Abstract: Solar flares, as strong explosions on the Sun’s surface, are well known driving agents that severely affect the near-Earth environment, producing additional ionization within the sunlit Earth’s atmospheric layers. X-ray solar flares can be classified regarding their effects on the lower ionosphere and its electron density profile. The focus of this research is on the study of disturbances induced by X-ray solar flares in order to predict the impact of possible weak solar events. In this paper we examined solar activity of lower intensity by conducting numerical modeling using several models and based on data obtained by very low frequency radio signals and from the Geostationary Operational Environmental Satellite (GOES) database on solar X-ray radiation.
