The luminary continues to spit on us. Spits often and strongly. Devices record the fourth powerful flash
The sun will not calm down in any way - for the seventh day it is behaving defiantly. On September 6, 2017, with an interval of only 3 hours, it flashed with two powerful flares - first of the X2.2 class, then - X 9.3. September 7 was followed by two more - one weaker flash of class M 7.3, the other very strong - class X 1.3. On September 10, “having accumulated strength,” the Sun again produced a powerful outburst, which scientists assigned an X 8.2. The same spot became the source of the flares. It is also an active region AR 2673, which rapidly formed on September 3 and began to "spark" on September 4.

The ejection of solar matter, which followed the X 9.3 flare and was directed directly at us, reached Earth over the weekend, causing a strong magnetic storm.
Now earthlings are more fortunate: the source of the X 8.2 flare - the very spot AR 2673 - has shifted to the edge of the solar disk during the rotation of the Sun. The ground has almost disappeared from the shelling - Venus will fall under it. Our planet, following the outbreak, "spit" of the coronal ejection will only touch the edge. However, solar matter is expected to reach Earth on September 13th. And yet it will cause a magnetic storm - albeit not very strong.
Active region 2673 has moved to the very edge of the Sun.
Active area 2673, which has been emitting powerful flares since the beginning of September.
In the meantime, our planet is bombarded by heavy particles - protons ejected by the Sun. Their density is very high, as evidenced by the images coming from the LASCO C3 space coronagraph, located on the Sun-Earth line at the L1 Lagrange point, one and a half million kilometers from the Earth. They are all strewn with hit marks.

Protons are charged particles. The magnetic field cocoon protects the Earth and its inhabitants from the harmful effects of their bombardment. Therefore, we are still alive.
Near-Earth satellites, as well as the Earth's ionosphere, which receives the main impact of the flash's hard X-ray and ultraviolet radiation, are experiencing an increased load.
The situation on the Sun is abnormal. Here is how it was commented on in the Laboratory of X-ray Astronomy of the Sun of the Physical Institute named after P. N. Lebedev of the Russian Academy of Sciences (FIAN):
“At the moment, despite the unexpectedness and incredible strength of the events taking place on the Sun, astronomers continue to view them as a one-time burst of activity - probably the last one before the long hibernation of the Sun, into which it should have fallen (and seemed to have already fallen) for the next few years … If this is the case, then most likely, the active region 2673 will not survive the full revolution of the Sun and will "die" on its reverse side, never returning to the field of view of the Earth. If this is not the case, and the ongoing burst of activity will continue or, moreover, will drag on until the end of the year, it will be necessary to admit that the Sun has experienced a rather serious deviation from the 11-year cycle, the possible consequences of which will still have to be understood.
In other words, events can develop in different ways. Therefore, further complications are possible.
Now there is a giant hole in the sun. The solar wind "comes through" from it. Its particles will reach Earth on September 13th.
