For the first time such a phenomenon has been discovered more than 40 years ago. As scientists have found, during periods of minimum solar activity normally closed magnetic lines in some areas may be open (especially at the poles).

As a result, the plasma is no longer held in the solar space and rushes into space. So there is a region where the plasma temperature drops sharply, and scientists see it in the X-ray as a dark spot – the coronal hole. Although its shape is constantly changing, it can “live” for more than five years.

Freed plasma becomes part of the “solar wind”, which significantly affects the ionosphere and magnetosphere of the Earth.

The result are different malfunction satellite systems electronics. It has long been established that such a “wind” affects the person. In any case, doctors advise people with chronic diseases, especially cardiovascular, exercise caution during magnetic storms.
