The European researchers defined scales “compression” magnetic field of Earth by extrass in the Sunshine. It turned out that the external border of the field, bedding above daily party of planet on a height about 60 thousand kilometres, can go down to 25 thousand kilometres. Information was collected by vehicles Cluster and Double Star during the large extrass of mass by a luminary, which happened in January, 2005 and December, 2006. Information of supervisions show that speed of streams of ions in the vinicity of planet as a result of extrass grew more than
in two times attained almost 900 kilometres in a second. Thus the general amount of the charged particles grew almost in five times, reported in a press-release ESA.izvestno, that the extrass of mass in the Sunshine can present a considerable danger for sputnikov and lines of electricity transmissions
on Earth. According to researchers, new results allow to estimate the level of danger. The presently scientific are engaged in development of suitable model, which would in number describe events, what be going on with the magnetosphere of Earth.Mission Cluster it is
from four identical vehicles which are revolved round our planet on an elliptic orbit. Sputniki were started in 2000 from a space center Baikonur, and quite recently the European space agency prolonged their work. Mission Double Star it was partly completed
in 2007.Presently a Sun is in the anomalously protracted period of a minimum of activity. Thus, however, to the Russian observatory of TESIS, located aboard sputnika "KORONAS-FOTON", it was succeeded to register the powerful extrass of matter on our
to the star, which happened 17 and on April, 23, 2009. Thus the streams of particles, emitted by a Sun, went by Earth. Scientists mark that, taking into account periodicity of what be going on flashes, it is possible to expect that next troop landing "will get" in our planet, passes Lenta.ru.
