In the years 2008-2009, had disappeared, sunspots almost entirely for two years.
The solar activity dropped to eim-century low. The solar physicists asked the open, where all the sunspots gone?
Now they know it clearly.
featured in their computer model, the scientists after the so-called dynamo process inside the sun that produces the strong solar magnetic fields.
climbing such magnetic fields in the depths, they can produce sunspots: they prevent the heat out the top to rise, causing the visible solar surface cools locally and darker. Overall, played by Nandy and his team 210 sunspot cycles, which in 1860 solar years corresponds They randomly changed the speed of the plasma circulation between 15 and 30 meters per second

However, while happy about all that they have discovered why the solar minimum as long has stopped, the sun spews out a flare for several days at a time. And not small as we can. See photo above.
