Il nostro amico (?) Sole

Abstract

The behaviour of our star, the Sun, also known as "Space Weather" may affect our technological society and our daily lives in various ways. Major events, already occurred in the past and not so unlikely, would have catastrophic effects on our civilization, heavily based on electricity, wireless communications and electronics. But even less disastrous (but much more frequent) solar anomalies might affect some of our critical infrastructures, such as the GNSS systems (GPS and Galileo), in terms of performance and availability. For this reason, increasing attention is being spent, also in Europe, on the study of the Sun and on the prediction of its anomalies.
