A giant coronal hole about a million kilometers in size has appeared on the Sun, reported the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences. Although visually the hole looks like emptiness, this is an illusion. It is created due to a strong drop in temperature and plasma density over large areas in the solar atmosphere. On the night of November 7, Earth will be caught in a stream of fast solar wind, which can cause magnetic storms. The effect will last for at least five days, and the geomagnetic situation will stabilize completely only on November 13-14. The video shows the coronal hole from November 1st to November 5th.
