The sun is a active stars, it support a strong, year after year in a changing, and about every 11 years around the Solar Max to reverse its direction [62].?The solar can cause a lot of influence, known as the solar activity, including in the surface of the sun's sunspots, solar flares, and carry the material through the solar system and the changing solar wind [63].?The influence of solar activity on Earth include auroras at high latitudes, and disrupt radio communications and power.?Solar activity are considered to play a very important role in the formation and evolution of the solar system.
The sake of the sun because the high temperature, all substances are gases and plasma, which makes the sun's speed may be faster at the equator (about 25 days), rather than high-latitude (about 35 days at the poles).?The sun's rotation caused by the lines over time entangled, causing the circle erupted from the sun's surface and trigger the sun to form the Department away from sunspots and solar prominences (see magnetic reconnection) for different latitudes of the poor.?With the sun every 11 years reverse its own, such a struggle to create a solar generator and the 11-year solar cycle of solar magnetic activity.
The solar wild car out of the sun itself, the magnetized solar wind plasma carries the sun's magnetic field into space, forming the so-called interplanetary magnetic field.?As the plasma along lines move away from the Sun interplanetary only at first along the radial stretch.?In the sun's equatorial plane in the sun above the equator and below away from the sun's has a different polarity, there is a thin layer of the current layer, called the heliosphere current sheet.?The rotation of the sun makes long-range magnetic field and current sheet rotating imaging is Archimedean spiral structure, known as the Parker spiral.?Dipole of the interplanetary strength than the sun is powerful.?Sun 50-400¦T the dipole (in the ball of light) as the cube of the distance attenuation in the distance of the earth, only 0.1 nT,.?However, based on spacecraft observations in the near Earth interplanetary as the value of 100 times, about 5nT.
