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 Stakes and became a successful broodmare, producing the 1000 Guineas winner Tideway and Heliopolis, a full brother to Sun Stream who was twice Leading sire in North America. Lord Derby sent the filly to his private trainer Walter Earl at his Stanley House stable in Newmarket, Suffolk.

Several major racecourses, including Epsom, Ascot and Doncaster, were closed for the duration of the conflict, either for safety reasons, or because they were being used by the military.
