The highly active sunspot is again directed directly at us. Here's what to expect:

The area of sunspots responsible for the magnificent auroraes that flickered over most of the Earth in early May has returned and is still engaged in machinations.
AR 3664, responsible for several X-class flashes, including the most powerful in the current solar cycle, left the reverse side of the Sun in mid-May. We couldn't see it while it was spreading, but then it appeared in style again.
When on May 27 it again bypassed the Sun's horizon under a new name - AR 3697, this spot flashed with another powerful X-class flash, this time X 2.8.
Since then, he has released four more X-class flashes, there were five of them in total at the time of writing this article.
On May 29, he released the X1,45 flash. On May 31, he released the X1.1 flash. and on June 1, he released two flashes: X1.03 and X1.4.
However, because of these eruptions, we are unlikely to see anything similar to the solar storms of early May. There have been no reports of a concomitant coronal mass ejection (CME) - the release of a huge mass of solar plasma and a magnetic field that creates the aurora when colliding with the Earth's magnetosphere.
This does not mean that AR 3697 is completed. Every day it emits weaker flashes. On June 2, it released two M-class flashes (this is the next level after X-class, 10 times weaker) and 10 C-class flashes, 10 times weaker than M-class. We are also unlikely to see a large effect from them, but the probability of new X-class flashes is high, about 30 percent.
The area of sunspots is now also located around the center of the solar disk. This means that any eruptions will be directed directly towards us. Of course, this is not a guarantee of CME activity, but the chances are much higher than average.
And we are currently approaching or at the peak of the 11-year cycle of the Sun's activity, which means that even if AR 3697 has already given us a better shot, there may be another area of sunspots that will give us another exciting light show in the coming months.
