Without our Sun, there would be no heat, no light and no life on Earth. An eleven-year cycle of magnetic activity modulates its appearance, and the occurrence of eruptive events such as flares and coronal mass ejections. I shall discuss how these, in turn, affect the Earth – and how the Sun currently does not seem to be behaving as expected.
