-The biggest task ever seen 10 years raises a big solar eruption to the Earth- ****************************** -Appeared on 17 October at the surface of the Sun, task AR 2192 group became the largest ever seen for many years with a close area of AR0496, the last large sunspot of the previous solar cycle, which covered 2610/1000000 of the solar disc on 30 October 2003, at the time where occurred the famous eruption of class X 45. -Forecasters believe that this group of sunspots is about as wide as the planet Jupiter with a diameter of 140 000 kilometres and some observers on Earth have even been able to see him at sunset, when the Sun is covered by clouds or mist. He was also very visible during Lunar partial eclipse Thursday, then the new moon passed between the Earth and the Sun, partially mitigating the sunlight. -Researchers from the NOAA Space Weather Prediction Center monitor very Pres this very active region on the Sun that has already produced dozens of eruptions of class (low) C, many eruptions of class M (average) as well as a classified eruption X 1.6 on 22 October. -Friday afternoon at 5: 07 p.m. EDT, AR 2192 produced another eruption of class X. The eruption had a very long and is valued at X3.1. It immediately caused a blackout R3 (strong) of the radio mainly at the level of the Pacific ocean. -The researchers have not yet determined if it was associated with a coronal mass ejection. -NOAA considers today 85% the chances of eruption of additional M class and 45% opportunities for another rash of class X. With the sunspot directly opposite the Earth, any coronal mass ejection would be geo-effective and could cause a geomagnetic storm potentially serious in the worst cases of the devastating effects on the electrical infrastructure and communication networks. -In the best cases, this solar storm could be confined to impressive lights. ******************************* youtu.be/yTnD3dC8IqE
