A large solar flare reaches Earth
The huge AR 1520 spot with a diameter ten times that of Earth, launched an X-flare 1.4, within the highest level in the intensity scale (there are A, B, C, M and X, points which is a number from 1 to 9). Whiplash has caused a coronal mass ejection (CME), a fiery cloud of particles and radiation that could affect Earth, as explained by the Space Weather Observatory.
The blaze has had consequences in South America, Central America and parts of the Caribbean, where there have been radio blackouts R2 level (high level).
Now, the National Oceanic and Atmospheric Administration (NOAA) study the path of the CME, according to EP. It is expected that the ejection of particles arrive on Saturday with a possible moderate to severe activity. NASA says on its website that the ejection travels to us to 1,367 kilometers per second.
If the rash is severe enough and the magnetic field direction of the particle cloud is perpendicular to the earth's field, the atmosphere will get a lot of energy, capable of damaging the communications and power grids. But this is only a possibility and, in this case, minimum, according to researchers. Due to the solar flare, they could be seen bright auroras in southern Canada and northern United States.
"There is cause for concern"
Experts have noted that the situation of the spot 1520, very focused on the solar disk, facilitate their arrival on Earth but "in no case would be cause for concern." This is the sixth class X flare so far this year. The first that was recorded in 2012 occurred on January 27 and reached a X1.8. Subsequently, the 1429 patch released three flares: the first on March 4 (X1.1) and two on March 7 (x5.6 and X1.3). Furthermore, on July 7 recorded a spot called 1415 , which reached X1.13.
The Solar Dynamics Observatory (SDO) spacecraft on Thursday captured the moment of eruption. Images can be viewed on the video on these lines.
