In just over a week the Sun has issued an unusually high amount of solar flares, which has baffled scientists at NASA. According to data from the agency since September 4 and in a little over a week on the surface of the sun they have produced seven different radiation emissions intensity. Among them, the most powerful flare of the last decade, which was observed this September 6th.
According to data from the Observatory of Solar Dynamics NASA (Solar Dynamics Observatory, in English), the behavior of the biggest star of our system is very unusual, because the stage of the cycle in which it is usually not register much activity.
The largest solar flare decade causes a very strong magnetic storm on Earth"The current solar cycle began in December 2008 and is now decreasing in intensity and moving toward solar minimum. It is a phase that these eruptions on the sun are once increasingly rare , "reads the report of the organization on the latest and largest solar flare intensity X9,3. "However, history has shown that despite this can be intensive , " he says.
The solar activity cycle changes every 11 years and now the sun is approaching its end. During this time the sun's activity increases and decreases. We are now in the ninth year of the cycle, when that should fade.
"Hybrid" possible cause stains flares
Some scientists believe that recent flares are not as strange as they might think. They have an explanation. For example, the director of the Observatory of High Altitudes the National Center for American Atmospheric Research (NCAR, its acronym in English), Scott McIntosh, believes that when the activity decreases the underlying magnetic systems to their spots appear to be in close contact close Ecuador.

In an interview with Gizmodo , McIntosh said that this makes the Sun produce "hybrid" sunspots. That is, regions containing magnetic fields that twist like water in the oceans of the northern and southern hemispheres.
"Remember how the Earth's rotation turns the water in each hemisphere in different directions? The sun does the same for the same reason, which is the Coriolis force," said MacIntosh. "These systems are very unstable it. Normally these types of stains produce the worst and largest eruptions and coronal mass ejections," he added.
