Solar wind Solar wind The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma consists of mostly electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV. Embedded within the solar-wind plasma is the interplanetary magnetic field. The solar wind varies in density, temperature and speed over time and over solar latitude and longitude. Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field. At a
Sun Stream the Rowley Mile to the adjoining July course. Ridden by Wragg, she won by three lengths from Blue Smoke, with Mrs Feather a further two lengths back in third. Sun Stream's success gave Lord Derby a seventh win in the race as both owner and breeder, and was very popular with the unusually large crowd. A month later, Sun Stream returned to the July course on 8 June for the Oaks Stakes. Although the race was not run at Epsom Downs Racecourse it was given its traditional name: wartime runnings at Newmarket had been known as the "New Oaks". The
