Geomagnetic storms and solar radio flux have both been studied in relation to daily changes. As a result, during storms, the level of ionosphere disruption and the severity of magnetic oscillations are both indicated by geomagnetic indices. According to this analysis, there would be almost no degradation in the HF band radio communications conditions if the magnetic field were to remain quiet. It shows that there are unsettled magnetic circumstances, which could mean that the HF bands for radio communications could suffer a little. Additionally, it shows that the situation is rapidly getting worse due to a significant storm that will probably cause a blackout in HF ionosphere propagation for several hours and the particles released at the sun’s surface by the natural occurrences. These solar flares are primarily composed of particles with thermal energy between 1.5 keV and 10 keV, such as electrons, protons, and alpha rays.
