It’s not the sun spots directly, but what’s actually causing the sun spots. Which is intense magnetic activity in the sun. This causes clouds of charged particles to hit the earth, this is called a geomagnetic storm, it can affect satellites and strong ones can affects power grids by inducing currents in conductors.
Geomagnetic storms occur when the sun sends out solar flares which cause irregular ionization of the ionosphere which in turn causes irregular refraction delays of a radio wave passing, a geomagnetic storm is a temporary disturbance of the Earth’s magnetosphere and ionosphere caused by a disturbance in space weather.
Geomagnetic storms are a solar-induced electromagnetic phenomenon which occurs both in our atmosphere and across the Earth’s surface. The variable flow of charged particles from solar flares through the earth’s atmosphere, which result in aurora. Are effectively electric currents; associated with these are fluctuating magnetic fields that in turn induce electrical currents across our planet’s surface.
Sunspots and problems with sattelites have the same cause: changes in the magnetic activity of the sun. These caus giant eruptions of electrically charged particles (which in turn cause said problems on earth) as well as changed gas-movement and heat distribution below and on the suns surface (which we can observe as cooler=darker spots).
