Series of 3 coronal mass distributions (CME) heading for Earth. The first two, launched by Class M solar sites on August 7, relatively small. Third, launched by X flare yesterday (more info below), yes more powerful. “Hitting Earth in succession on August 9/10, 11 and 12, the 3 CMEs could spark geomagnetic storms strong up G3 class with mid-latitude auroras in the United States and Europe,” reports the special website SpaceWeather.com.

The CMEs, the X-class flare and the incoming geomagnetic storm

Sunspot AR3777 produced its most powerful flare yet, an X1.3 class explosion (August 8 (9:35 p.m. ET).) NASA’s Solar Dynamics Observatory recorded the ultraviolet flash.

“Radiation from the flame ionized the Earth’s upper atmosphere and caused shortwave radio blackout from North America to the Hawaiian Islands. Sailors and amateur radio operators may have noticed a loss of signal below 30 MHz for an hour after the flare,” reports SpaceWeather.com. The most interesting is the coronal ejecta (CME). Immediately after the flare, SOHO coronagraphs detected a cloud of solar plasma heading for Earth.

“This CME is moving at speeds above 1,000 km/s and is likely to arrive on August 11th, adding to its impact with 2 CMEs already on the way.“. NOAA predicts the arrival of “early August 12“). The impact could push geomagnetic storm levels into the G3 (strong) category with mid-latitude auroras in the United States and Europe.

What is a flame

And white sun it is a burst of energy on the surface of the sun that occurs when magnetic field lines, near sunspots, break and reconnect. This free magnetic link a large amount of energy in the form of electromagnetic radiation that covers a wide spectrum, from radio waves to gamma rays. Sunburns can last from a few minutes to several hours and they are classified according to their intensity in classes A, B, C, M and Xwith class X representing the most powerful flames. These events not only increase the brightness of the Sun, but they can also accelerate high-energy particles, affecting interplanetary space and possibly the near-Earth space environment.

What is shortwave blackwave radio

And radio blackout where to cut on Earth, caused by a solar flare, is a disruption of radio communications that occurs when a flare emits large amounts of electromagnetic radiation. This radiation ionizes the upper layers of the Earth’s atmosphere, especially the atmosphere ionosphereincreasing the electrical density. The ionosphere, which normally reflects and transmits short-wave radio waves, becomes too dense and saturated, preventing the reflection of radio waves and causing communication breakdowns. These burns last from a few minutes to several hours, depending on how intense the flame is and how long it lasts. The effects are particularly visible in the regions that are illuminated by the Sun during the lighting.

What is a coronal mass ejection (CME)

And’coronal mass distribution (CME) is a large burst of plasma and magnetic fields from the Sun’s corona, the outermost part of the Sun’s atmosphere is caused by the instability and reconnection of the Sun’s magnetic field lines, which release out a lot of energy. When a CME occurs, large bubbles of magnetic gas are ejected into space at speeds reaching millions of kilometers per hour.

CMEs can have a huge impact when they hit Earth. They can cause storms geomagneticwhich could affect communication and navigation systems, damage satellites and affect electrical grids. Constricted particles from CMEs can also increase the intensity of the Northern and Southern Lights.

What is a geomagnetic storm

A a storm geomagnetica It is a temporary change in the Earth’s magnetic field caused by the interaction between the the wind of the sun and the Earth’s magnetic field. When high-energy particles from the solar wind hit the Earth’s magnetosphere, they induce electric currents in the polar regions, creating spectacular auroras and distortions of magnetic fields. Geomagnetic storms can be the result of coronal mass ejections (CMEs) or strong solar wind streams. They can cause disruptions in electricity grids, satellite navigation systems, telecommunications and air and sea navigation services.

What are the Northern Lights

The morning boreal they are amazing light phenomena that occur mostly in the polar regions, seen especially near the North and South Poles. When the solar wind, which is made up mostly of electrons and protons, hits the Earth’s magnetosphere, some of these particles are directed along magnetic field lines towards the poles. Here, these charged particles interact with gas atoms in the upper atmosphere, usually oxygen and nitrogen, causing them to explode. When the excited atoms return to their normal state, they release energy in the form of light, creating beautiful, colorful auroras.

The Northern Lights can take on different forms of us, violin e rossodepending on the height of the interaction and the type of atoms involved. These light shows can be seen especially on polar nights, when the sky is dark and the atmospheric conditions are favorable. Studying the Northern Lights will help us better understand the interaction between the solar wind and the Earth’s magnetic field, as well as physical processes in the Earth’s upper atmosphere.
