Astronomers say that an interval of 11 years the Sun reaches its peak activity and solar flares emit a huge amount of radiation. When these rays reach the earth problems, from satellite communications to those related to cardiovascular diseases. Solar eruptions unprecedented scale, dark spots on the planet surface. Effect on the Earth: magnetic waves that disrupt electronics and satellite communications, increase cardio-vascular and nerve, producing an unprecedented heat wave. "What happened to Sun?", Is the question that preoccupied him simple people, and researchers. "The highest levels of ultraviolet rays in the last millennia. I came to this conclusion after we examined the deep layers of polar ice caps. Isotopes depending on the" register "in these layers we can see that solar activity has been over time. The year 8000 was not so intense activity, "said Professor Sami Solanka, Max-Planck Institute for solar system study of the German town of Lindau. German researcher believes that this very strong solar activity will take several years before the sun to "calm down". "Until the Sun's magnetic field will stabilize must deal with these solar eruptions, with adverse effects to human health," says Professor Solanka. Astronomers and fears are shared by meteorologists. Since measurements are made in Germany have recorded the highest temperatures for May. "Most worrying is that in hot weather include more northern areas," explains Helmut Malewski meteorologist. Temperatures in the solar atmosphere are very high, which is why gas is formed in the plasma state. under these conditions, the atmosphere is strongly influenced by magnetic fields as a cross. These magnetic fields, and the solar corona, the last layer of the Sun's atmosphere, is expanding into interplanetary space as part of the solar wind. The appearance and movement of sunspots and solar flares have a 11-year cyclical. I mean every 11 years the Sun has a maximum activity, then the middle of this period there is an activity minimum. The same cycle is observed and some terrestrial phenomena as disturbances of the ionosphere or the earth's magnetic field, the frequency of polar auroras, the growth rate of trees, and others directly affected by the Sun through a corpuscular radiation that crosses the Sun-Earth distance in a -2 days, which lead to abnormalities in the propagation of radio waves on Earth or, often, the birth of magnetic storms. The particle flow is derived from the Sun and the origin of polar auroras.

This magnificent spectacle of color is due to material expelled from the sun interacting with Earth's magnetic field. behind powerful solar explosions are highly charged particles expelled into space to travel through space energy at rates ranging between 300 and 1200 km / s. A "cloud" of such particles forming the plasma. Plasma flow coming from the Sun is known as the solar wind. while the edges of the solar wind interacting with Earth's magnetic field, some particles are attracted to it. They then follow magnetic field lines down to the ionosphere, the atmospheric layer located between 60 and 600 km above the earth. When these particles interact with gases in the ionosphere to produce this impressive light show, better known as aurora. Results of biological effects has been emphasized thickness variation of annual growth rings of trees, which shows thickening sensitive to every 11 years. Also "biological clock" of migratory birds are suffering some disorder in these periods. Many of the birds sent to training sessions or cone-courses were not returned home, this is one of the signs of disorder of the Earth's magnetic field. "The year 2000 saw a solar activity maximum, then this activity should be decreased so that in 2006-2007 to reach a minimum solar activity. Not only did this not happen, contrary to amplify the solar explosions inexplicably . auroras appeared both in the southern hemisphere, but also in the north, near the magnetic poles.
High temperatures to be announced this summer. Solar Explosions and thermometers were messed. European countries have announced above average in the last days of May. For this time of year the National Meteorological Agency announced that earlier this week temperatures are 6 degrees above the annual average, and this situation will be extended in the future. The highest temperature at the end of May was 40.8 degrees was recorded in Romania in 1950, in Baraganu Plain.
