The loaded particles, which have been thrown out by the Sun during four powerful solar flares in previous days, reached to the Earth. The American GOES satellites fix growth of concentration of protons in near-earth space. The weak proton solar flare testify the forecast of the center of space weather of National administration of oceanic and atmospheric researches of the USA (NOAA)
These are the remains of streams, which were injected by earlier active area 1748 at east edge of the Sun. The main streams passed by. The astronomers don’t expect any dangerous phenomena.
Since Monday on the Sun there were four powerful x-ray flashes of the highest class X, which weren’t observed since October, 2012. Each such solar flare was accompanied by emissions of solar plasma and the loaded particles of high energy. Their source is group of 1748 spots, which was at east edge of the Sun therefore emissions took place and passes by the Earth, and won’t cause magnetic storms.
Now in near-earth space is observed growth of concentration of protons with energy about 10 megaelectronvolts. The stream of these particles exceeded level in 10 particles on square centimeter in a second. It corresponds to the minimum proton event of S1, which can cause only small hindrances for communication in Polar Regions.
