On the Sun formed a huge coronal hole

The Sun formed a huge coronal hole, which is directed directly to the Earth. The coronal hole is a source of high-energy and high-speed solar wind (a flux of solar particles), which interacts with the magnetosphere into an excited state, resulting in magnetic storms and polar auroras.

The white lines in the photo are closed magnetic fields, in the coronal hole these fields are opened, which causes the solar wind to flow into outer space. It should be noted that the coronal hole in the optical range is not visible.

At this time, the solar wind velocity is ~ 729 km / s. (~ 2 times higher than normal). Now on Earth, a magnetic storm is raging, which will intensify in the next 24 hours.
