I recently joined a Space conference in Rome where I learned that the famous solar storm called "Carrington event" taking place in 1859 causing severe defects to the telegraph system as far South as Texas was maybe not the biggest solar event ever. A recent publication shows evidence for an event that was 10 times larger.
We usually base our worst case scenarios on the Carrington event. Have we been grossly underestimating solar storm risks? Solar storms what could they do?
Solar storm can damage satellites, disturb radio communication of airplanes, distort GPS signals and maybe even destroy transformers, which could potentially lead to prolonged power outages.
