LOS ANGELES, Nov. 5. / Itar-Tass Kachalin /. Solar Dynamics Observatory, USA / GSO — American scientific satellite / register one of the most powerful solar flares. Activity in the area luminary capable soon cause a series of new disturbance slowly moves to the point facing the Earth. In this position, area of activity will remain two weeks, predicts the National Oceanic and Atmospheric Administration of the United States.
Flare that occurred on the Sun on Thursday, in line class X1, 9 / Latin letter / and "provoked after about 45 minutes of radio communications infringement on Earth," NASA informed. "Scientists continue to monitor the area of activity in the star, which may give rise to a further surge in solar activity," — said the U.S. space agency.
It recalls that the signs of the activity lights are associated with so-called sunspots, whose number currently amounts to several dozen. The largest is the spot from the directory called AR11339, up to 80 thousand kilometers in length, and is several times wider than the disk of the planet. In this zone, on Thursday there was a powerful coronal mass ejection — a hot plasma / flux of protons, electrons and heavy elements /, and ran in the direction of Venus.
According to the National Oceanic and Atmospheric Administration of the United States, five days is the largest area of activity will shift so that the flow of new coronary emissions / if they happen / will be directed straight to the ground. "This area will be converted to the planet for two weeks," — said senior researcher Joe Kunches management.
Coronal mass ejections, depending on the brightness of their production of X-rays are divided into five classes: A, B, C, M, X. The strongest — emissions or flare of class X, subsequent class is 10 times weaker than the last. For the earth is a dangerous class M or more. The most dangerous is class X, especially when the velocity of the plasma ejected from the corona lights, more than 1.6 million kilometers per hour, and the weight of up to 10 billion tons. Such phenomena can lead to the change in performance of satellites, ground-based communications and cause magnetic storms, but the immediate danger to the person does not represent.
NASA summer recorded in the Sun class resentment X6, 9 February — Class A2, 2, and in December of 2006 — Class X 9.
