The largest in 20 years, Sunspots, which "looks" on our planet, can cause solar storms of abilities cause power outages, scientists say NASA.


Sunspot AR 12192, which could fit ten planets the size of Earth, turned to the globe in October, but did not produce coronal mass ejections - incandescent matter spewing into space at a speed of 6.4 million km / h, writes Mashable.com . As you know, coronal mass ejections cause magnetic storms and often interfere in the work of communications satellites and power grids.

In early November, the stain disappeared from view for two weeks, but now it is again drawn to the Earth. During the "vacation" spot reduced in size, but NASA experts Holly Gilbert argues that the risk of increased solar storms.


Sunspots are regions of strong output in the photosphere (up to several thoUSAnd gauss) magnetic fields. Darkening of the photosphere due to suppression of the magnetic field of the convective motions of matter and, as a result, decrease the flow of thermal energy transfer in the relevant fields.

In size AR 12192 occupies 33th place among the scientists recorded since 1874 32,908 Sunspots. Over the past 24 years, it is the largest. In October and November, the spot produced six major outbreaks, and many smaller ones. According to Holly Gilbert, surprising that these outbreaks are not completed a coronal mass ejection. There is a possibility that it will happen in the coming days.

AR 12192 will diminish and fade away, but before it commits another circle on the surface of the Sun. The nearest star is now in the phase of low activity, and scientists expect that Sunspots will appear less often.
