On the sun began Heavy Duty Activity


As the spaceweather.com, sun spots on the eastern limb of the Sun explode powerful X-class solar flares.

Spot at number AR1748 announced itself in the early hours of 13th May X1.7-class eruption, and then quickly followed by an outbreak level X2.8 year and even more — X3.2, but on May 14. This is the most severe outbreaks this year, and they signal a significant increase in solar activity. NOAA forecasters estimate the probability of new X-flares during the next 24 hours in 40%.

All these outbreaks produced strong emission of extreme ultraviolet radiation. Here is the last eruption having level X3.2 points on the Richter scale of solar flares, obtained by NASA's Solar Dynamics Observatory:

The explosions produced as emissions into space coronal mass (CME). Coronagraph on board the Solar and Heliospheric Observatory monitor these clouds of plasma.

In the animation is visible to the planet Mercury. Although it seems that coronal mass ejections hit the Mercury, in fact, this is not happening. No planets were not in that moment on the "line of fire". However, the cloud coronal mass apparently hit the spacecraft NASA "Spitzer" on May 15-16.

When events on the Sun began on May 13, guilty of them spot (number "AR1748") was hidden behind the eastern limb of the Sun, but now the rotation of the sun makes the visible active region. Solar and Heliospheric Observatory captured the first shots of just a few hours ago:

Powerful solar flare, the likes of which has not happened since last fall, recorded twice in the last day. However meteozavisimosti people should not be afraid of magnetic storms. "The situation is not geo-effective source of the outbreak, the charged particles ejected at the time of the flash will not fly in the direction of the Earth, and hence the magnetic storm is very unlikely," — RIA "News" to the director of the Center space weather forecasts of the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (Troitsk), Sergei Gaidash.

First class flare was recorded on May 13 at 06:17 MSK, as suggested by data center space weather forecast of the National Oceanic and Atmospheric Administration of the United States (NOAA). The second occurred at 20:16 MSK in the active region, located on the eastern edge of the Sun. Both emissions are class X — the most powerful on the classification of NOAA. According Gaidash, this pair of flares was the strongest surge in solar activity from October 23, 2012.

Solar flares coincided with a heat wave that came in the Capital Region early. In recent days, the average temperature in Moscow exceeds the norm by eight — nine degrees. This situation will last for the entire first half of the week: In some places the temperature reaches +31 ° C, "Vesti".

Closer to begin Thursday showers and thunderstorms, and the temperature will drop to 23 … +28 ° C. By the weekend, rain will stop, and the heat of re-intensify. According to him, the leading expert of the Center of weather "Phobos" Vadim Zavodchenkova, a fundamental change in weather should wait until Sunday: will an active storm front that will bring cool air from the north. The temperature will drop to 21 … +26 ° C. And in the coming week, the thermometer back into the framework of the norm.
