The solar wind is a stream of plasma, charged particles created by collisions of atoms in the intense heat of the sunâs atmosphere, or corona. These charged particles, mostly protons and electrons, have their own magnetic field. They reach Earth at speeds of 350 to 400 km per second.riginating in an atmospheric layer high above the surface of the Earth, auroras are generally seen at altitudes between 100 km and 500km. They are most frequently seen in the auroral ovals, which are two rough circles centered on the magnetic poles of the Earth with a diameter of about 3000 km.
