ocr: SOLAR PHENOMENA The magnetic field may form loops on the surtace of the Sun. In these areas the emerging energy is partly blocked leading to a lower surface temperature. We cans see these areas as sunspots. In close proximity to sunspots, the strength of the magnetic field may multiply over 3,000 times. Sunspots are part of active regions where powerful flares and eruptions occur. The one million de- grees (Celsius) hot, outermost layer of the Sun, the corona, ex- pands outwards as the solar wind. The solar wind carries plas- ma through the solar system. Luckily our planet and life on it is pr ...
