The threw suffered a major solar eruption yesterday afternoon, sending waves of radiation into and causing a brief interruption in communications in certain parts of the Earth. The eruption occurred in the area AR 11598 sun, and peaked at 03:22 GMT, according to the observations of the Solar Dynamics Observatory (SDO) spacecraft.

The eruption was rated x1.8 level, one of the strongest types, according to Weather Prediction Center in Space (SWPC) in the United States.

Solar flares occur when magnetic activity increases in certain areas of the sun’s surface. Scientists measure the power of an eruption in energy classes, being the “class X” the most powerful. Other more moderate eruptions qualify as type M solar storms and auroras can recharge on Earth when aimed at us. A rash type C is the weakest group and has little effect on our planet.

Monday’s eruption was captured in photos and video (at the end of the note), and looks like a white light coming from the sun. The eruption was of type “impulsive”, which quickly disappeared. “Impulsive flares are not normally associated with space weather, and in addition, this region is still several days to face directly to Earth from its central disk. However, the potential for continued activity continues, so stay tuned for updates as the 1598 Region visible progress on the disc, “said SWPC .

Solar flares often thrown charged plasma (called “coronal mass ejection”) into space, that when they hit the Earth can cause geomagnetic storms that disrupt radio communications and power plants, creating beautiful auroral pass. This eruption did not throw an ejection of this type, and it is estimated that the effect on Earth is limited. The large amount of radiation, however, was able to disrupt some radio communications.

The sun is rising in activity in recent times, and is expected to magnetic activity reaches a peak in 2013. This type of activity increases and decreases in periods of 11 years. “Humans have recorded this solar cycle continuously since it was discovered in 1843, and is normal to have several outbreaks a day during the peak activity of the sun,” NASA said.
