A new model to predict the electron density and effective recombination coefficient of the lower ionosphere under solar flare conditions is presented. This model relies on space-borne solar irradiance measurements in coincidence with ground recorded

In this study we analyze the Ground Level Enhancement Event No 70 observed on December 13, 2006, by correlating the observations from two research topics: Cosmic rays and Very Low Frequency (VLF www.swpc.noaa.gov ) and Pamela ( www.pamela.roma2infn.i

The classification of X-ray solar flares is performed regarding their effects on the Very Low Frequency (VLF) wave propagation along the Earth-ionosphere waveguide. The changes in propagation are detected from an observed VLF signal phase and amplitu

VLF amplitude enhancements of the NAA/24.0 kHz signal (Maine, USA), registered by the Belgrade AbsPAL facility during solar flares, have been related to solar X-ray fluxes measured by the GOES-12 satellite. The observed regular appearance of the VLF

The diurnal variations of fbEs in 1 MHz intervals for any month, usually can be adequately represented by Pearson's Type I and II distributions. The distributions of h'Es show sequential decreases with time. Assuming a relation between fbEs and Ne(Es
