Abstract

This project aims to study ionospheric disturbances on a global scale during Solar flare (SF) and coronal mass ejection (CME), in solar cycle 25. The study will be carried out using experimental data from VTEC, ROT and ROTI. Ionospheric electrodynamics will be studied during positive and negative ionospheric storms on a global scale. Where positive and negative ionospheric storms are considered when the ionospheric density is greater or less than the average density during calm days, respectively
