The number of sunspots, which is considered the main characteristic of the level of solar activity rapidly drops to zero: currently facing the Earth side is not observed any spots, is spoken in the message of laboratory of x-ray astronomy of the Sun Physical Institute named Lebedev, Russian Academy of Sciences (FIAN).

«Are there any spots on the opposite side of the Sun, hard to say, but based on the images of the Sun two weeks ago when this side was turned to the Earth, spots are missing and there. Thus, our star is now very close in appearance to an ideal object, without any «shortcomings» and how it represented the people before the beginning of the 17th century,» the researchers note.

The number of sunspots is the main parameter that is measured by the 11-year solar cycle, whose history goes back almost 270 years. Every 11 years the number of sunspots reaches a maximum, and about midway between these peaks is reduced to a minimum value called the solar minimum. The nature of these changes has remained unclear for nearly 200 years, and only in the mid-twentieth century it was found that increments of 11 years is changing magnetic field of the Sun (alternately intensified and attenuated).

As spots form in areas of strong field, in the moment of maximum field strength reaches a maximum, and the number of spots. Magnetic and associated electric energy of the Sun are the main «fuel» for solar activity (solar flares and emissions of substances are based on electric and magnetic in nature). For this reason, in the peak years of the solar cycle is growing and «bursting» activity of the Sun. In the years of low, on the contrary, decays.

Based on the pattern that we are seeing now, the Sun is inexorably moving to the next minimum, which is reached at the end of 2018 first half of 2019. In this way the Sun must first be solved forever complex group of spots and related solar flares, which apparently has already occurred. Then in the Sun’s corona the IP and gradually begin to emerge new magnetic field flows, there are the first spots, and the flywheel of the solar cycle begins a new 11-year turnover.

At the moment the Sun began to enter the third stage, characterized by gradual disappearance of the spots. At this stage still for a short time, can appear some spots and even occur the weak flash, but it is only the last fading bursts of activity. The final disappearance of the spots from the Sun could happen in the next 2-3 months.

Concerns about whether there is the Sun of a new low, and if it isn’t crashing, which it will remain in it, to speak out when approaching each solar minimum. Over the past 200 years, however, the repetition of the situation with the Maunder minimum (a period of long term reduction in the number of sunspots, from the mid 17th to early 18th centuries) was not. From what is visible on the Sun now, its evolution is not yet in full compliance with the behavior that was observed during the previous 11-year cycles.
