Last Thursday (October 28) the sun’s surface reached A series of X-ray bursts, including the most powerful of this solar cycle, Class X1.0As the plasma cloud began to rush towards Earth.
According to NASA, the solar wind is full of charged particles, It will reach the magnetic poles of the Earth on Saturday (30:10) or in the night from Saturday to Sunday (30 / 31:10), causing a strong geomagnetic storm in the ionosphere and exosphere.
It will show the amazing Northern Lights, which will be admired not only by the inhabitants of the Far North, but also by us. The latest forecasts indicate Geomagnetic storm of at least G3 (Kp = 7)This means that the dawn will also dance over Poland.
The stronger the storm, the more colorful the Northern Lights and the greater the sky coverage. To see it you have to go to a dark placeSheltered from artificial lighting and looking towards the northern sky. With a stronger storm, the Northern Lights could be seen even at its peak.
However, severe geomagnetic thunderstorms also have a dangerous face, as they can cause Interfere with radio and satellite communicationsand damage sensitive electronic devices and the power grid.
At dusk, airline passengers, as well as astronauts were on board International space station, receiving more radiation than usual, which may affect their health.
Northern Lights It forms in the upper layers of the Earth’s atmosphere, in the ionosphere and exosphere, at an altitude of 65 to 400 km above the surface, usually at a distance of 20 to 25 degrees from the north magnetic poles and south.
The amazing colors of the aurora are due to the interplay of particles solar wind with air particles. The streaks are usually red when combining with nitrogen and green when reacting with oxygen. Other colors including pearl, pink and purple mix them.
