Detailed explanation-1: -Ionospheric expansion can increase satellite drag and make their orbits difficult to control. During magnetic storms, satellite electronics can be damaged through the build up and discharge of static-electric charges. Astronauts and high altitude pilots can be subjected to increased levels of radiation.
Detailed explanation-2: -This gust of solar wind disturbs the outer part of the Earth’s magnetic field, which undergoes a complex oscillation. This generates associated electric currents in the near-Earth space environment, which in turn generates additional magnetic field variations–all of which constitute a “magnetic storm."
Detailed explanation-3: -A geomagnetic storm is a disturbance on Earth’s magnetic field caused by a solar flare or exchange of energy from the sun. The strength of the storm is measured in classes, G1 to G5. G1 being the weakest and G5 being the strongest. NASA reported a massive solar flare erupted from the sun Wednesday afternoon.
