Powerful flash Solar Dynamics Observatory recorded by NASA October 20, 2012. According to X-ray intensity flash awarded class M9. This means that it may have little effect on space weather near Earth. If we consider that these cosmic phenomena are measured on a scale of 1 to 10, this flash is one of the most powerful class of M. However, the strength of the energy she is still a long way from the flares of class X.

Indeed, such an event was not long in coming. October 23, 2012, at about 7:00 am Moscow time, the Sun was an outbreak, which experts attributed to a class X1.8. Fear for those who are on the earth's orbit, the equipment at this time is not necessary — magnetic storms or increase the flow of charged particles near Earth at this time is not expected, because the active area is on the edge of the disk lights and is not directed toward Earth ..
NASA also reported that eight hours earlier in the same area of the sun took place just two less powerful flash — Class M5. In addition, this area was recorded coronal mass ejection — solar plasma consisting primarily of electrons and protons. These particles can reach our planet in a few days and cause interference to radio communications.

To increase the number of solar flares is not surprising. We are dealing with a 11-year cycle of solar activity, which was opened in 1843. Now the star is in the active phase, the peak of which will be in 2013, and then begin declining.
