The sun attacks the Earth with double blows

Using the Green Bank Observatory (West Virginia), scientists were able to observe radio signals from the MESSENGER spacecraft. It turned out that solar eruptions, leading to failures in communications and the power grid, are endowed with secondary consequences when approaching the Earth.

Emissions of coronal mass (ACM) are powerful massive solar eruptions that can lead to geomagnetic storms. VKM is often associated with solar flares. The most powerful emissions are able to move at a speed of 2000 km / s, flying past the Earth in a matter of seconds. It was possible to find reconnection areas going for VKM at a speed of 750 km / s. It turns out that the influence of ECM on the weather includes the initial impact and secondary impacts from powerful electric currents and accelerated plasma.

The picture shows Mercury, regarded as the bright point on the right. He was watched by the MESSENGER spacecraft. Radio signals from the ship investigated the observed near the solar environment Such events can affect human activity and technology not only in space, but the atmosphere and the Earth. In 1989, a powerful VKM caused problems with satellites in Earth orbit, the space shuttle Discovery and electrical networks, due to which 6 million Canadians lost their electricity.

Previously, it was not possible to see the secondary VKM areas, because there were not enough opportunities to explore this area with spacecraft. The MESSENGER, which revolves around Mercury on the other side of the Sun, is located in the right place and takes time to observe the VKM in a safe position and transmitting signals to Earth. Understanding the three-dimensional structure of eruptions affecting the Earth, will prepare for the potential consequences.
