Introduction
I am currently working in the solar division of Center for Research in Astronomy and Astrophysics Geophysics. We are researching ionospheric disturbances due to geomagnetic storms using VLF signals.

At night free electrons of the lowest ionosphere are either lost by recombination with positive ions, or by attachment to neutrals thus forming negative ions. Whereas for ionisation photons of at least UV energy and/or energetic particles are required, visible light suffices to detach electrons from neutrals. One could compare mesurements of nights...
This paper investigates the impact of a powerful gamma ray burst (GRB) that occurred on 9 October 2022, on the Earth's environment using a very low frequency receiver (VLF) to probe the lower ionospheric region (the D region). In addition to the VLF data analysis, we employ numerical simulation through the Long Wavelength Propagation Capability cod...

The effects of one super and two intense storms on three European very low frequency (VLF) transmitter signals received at Algiers (Algeria) station, are presented. Two VLF transmitters (DHO and GQD) are located almost at the same mid‐latitude and third transmitter (NRK) at a high latitude, allowing us to study the latitudinal dependence of the sto...
