For the most part, the Earth’s magnetic field protects humans from the barrage of radiation which comes from sunspots, but solar storms can affect satellite-based technology.
Solar winds can heat the Earth’s outer atmosphere, causing it to expand.
This can affect satellites in orbit, potentially leading to a lack of GPS navigation, mobile phone signal and satellite TV such as Sky.
Additionally, a surge of particles can lead to high currents in the magnetosphere, which can lead to higher than normal electricity in power lines, resulting in electrical transformers and power stations blowouts and a loss of power.
