How Solor and Geometric Storms affect the earth

On Sunday May 12th the largest solar storm was recorded. Solar Storms affect us according to article ,"Study Will Explore How Solar Storms Affect Earth's Atmosphere" by Edwin L. Aguirre to those who are in high altitudes like when flying in planes or walking in outer space because of the auroras which is the high energy particles produced by the storms can harm there health. Geomagnetic storms can causes a surge in a electrical current overloading electric power grids and damaging transmission lines and oil pipe lines. This to me I find very interesting because there are storms that are not even happening on earth and far from us can still affect us and our lives on earth and no one even knows it.
