solar Corona is the outer atmosphere of the Sun extends millions of kilometers from the surface of the star consists of a very thin plasma with a temperature of approx. 2 million degrees C. Well seen the faint glow during a total Eclipse of the Sun.
Appear in her sometimes dark region visible in the range of ultraviolet waves and x-rays, which are called holes koronalnymi. This is the place where the magnetic field lines of the star are not “closed”, which causes an escape from the Sun, strong and fast flow of charged particles. Blowing out of the holes koronalnych the solar wind is two times faster than normal.
Big hole koronalna that at the end of October opened over the Sun, bathing the Earth in a stream of such heated solar ions, which caused the average power of the storm geomagnetyczną above the Ground, and continuing for almost a week, the Northern lights in the Arctic.
It was a huge hole that covers almost half of the solar disk. After a few days was directed towards the Earth, and then turned together with the rotating Sun and disappeared on the other side of the star, invisible from Earth.
Now the same hole is returned, – said NASA. Appeared again during a continuous 27 days, the rotation of the star around its axis
Bit however, and no one to listen to, but even more – now occupies about one third of the stellar surface. Yesterday I removed it, the Solar Dynamics Observatory, one of NASA satellites:
NASA/SDO
Scientists predict that the blowing of this hole fast wind hit the Earth even today.
a Cloud of charged particles from the Sun can neutralize the earth’s magnetic field that protects us from cosmic radiation. Without this natural barrier the charged particles from the Sun, mostly electrons penetrate the atmosphere and cause storm geomagnetyczną.
Its consequences are deplorable. Extremely powerful currents of magnitude of millions of amperes, which, during magnetic storms originate in the ionosphere, causing new currents in the earth’s crust, and by the way, all good conductors on the surface of the planet – rails, Railways, pipelines, Intercontinental communication cables and wires electric traction.
David Whitehouse in the book ‘the Sun’ writes that such induced currents accelerate corrosion of the pipelines that the June 4, 1989. this has led to the explosion of a Siberian gas pipeline, in which burned two passenger trains and 500 people were killed
Also in 1989, the excited currents smashed the canadian energy protection network and a half-day pogrążyły in the dark the entire province of Quebec, were closed to metro and airport, the traffic lights didn’t work.

This time, however, the forecasts are not alarming. The us national weather Service Ocean and atmospheric (NOAA) predicts that the upcoming storm will reach force G1, i.e., the smallest in pięciostopniowej scale.
this Means the possibility of small noise in the transmission systems of energy and also a small risk of interrupting some satellites
In Arctic areas is likely to occur the Aurora. Charged solar particles collide with air molecules, a hundred kilometers above the earth and cause them to glow, as in neonówce. Oxygen molecules, give Shine color, red and yellow, and nitrogen molecules also Shine red, and the hydrogen and helium in shades of blue and purple, more difficult to see against the night sky.
to catch up with rivals happiness, if the interference from the magnetic field of the Earth is more than say the forecasts, it is possible that the dawn will Shine over Poland. So tonight after sunset, look to the North horizon, if the weather will not fail.
