In the last hours, the Sun has emitted powerful bursts of radiation into the atmosphere that NASA has captured from the Solar Dynamics observatory. Specifically, two very powerful on the morning of September 6. This is the most powerful emissions released by the Sun in the last 12 years. The first, intensity level X2, occurred at 11:10 Spanish time. And the second, level X9, three hours later. Two other bursts have also been registered on the morning of September 7.
The X9.3 eruption was the largest so far in the current solar cycle, during which the Sun's activity turns on and off. The current solar cycle began in December 2008, and is now decreasing in intensity and heading toward solar minimum. This is a phase when these flares in the sun are increasingly rare, but history has shown that they can be intense.
Solar flares are powerful bursts of radiation that the Sun emits in cycles of a decade. This radiation is so powerful that it can interfere with satellites and damage our power grids. And its effects have been noticed on Earth.
Hours after the event, failures have been recorded in the high-frequency radios ; in addition, the GPS signals lowered their intensity for an hour. In 2003 the most powerful eruption ever recorded took place. It was level X28, and it overloaded all of NASA's measurement sensors.
In the next few hours, even more consequences are expected , when the radiation reaches our planet with greater intensity.
