The Sun is the closest star to us at about a distance of 150 million kilometres. Its energy is generated by nuclear fusion, from which high energy photons are produced. The interior layers of the Sun are the Core, the Radiative zone and the Convection zone, while the Photosphere, the Chromosphere and the Corona make up the Solar atmosphere.

Before we can talk about Space Weather, we need to understand about the Sun’s magnetic field. While the solar magnetic field is complicated, to simplify, we can say that like Earth, the Sun too…
