Although the sun is so far away that even its light takes eight minutes to reach us, it is still so close to us that the space near the earth and the earth's magnetic field in particular are always badly affected by violent eruptions - and sometimes our electronics, which are becoming more and more sensitive in infrastructure and communication structure …
