On the Sun formed a huge coronal hole

On the Sun these days in the x-ray range there is a rather large coronal hole formed as a result of the opening of the magnetic field of the star and is a source of high-energy and high-speed solar wind (~ 600 km / sec). On September 25, 2017, a geomagnetic storm is probable on Earth with a probability of 50% and the appearance of auroras, as a result of the interaction of the earth’s magnetic field with the solar wind.
