Solar flares reached to the Earth

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.

The Most powerful solar storm on May 12

People of Earth were lucky that the most powerful solar flare, which took place on May 12, was on the other part of the Sun. On May 12 on the Sun was observed one of the most powerful solar storm of 2013. It was recorded by sensors of orbital Observatory Solar Loudspeakers (SDO). The purpose of this program is development of the scientific knowledge necessary for the effective solution of aspects of Solar and Terrestrial communications, which directly influence life and society. Solar storm was referred to the class X1.7. The class X is the most intensive level of solar flashes. The index specifies value of intensity of flash and can be from 1,0 to 9,9. Such powerful solar storms can pose serious threat for ISS crew, and also for the complex of a space station and other space satellites. Worst of all that such flashes can’t almost be predicted in advance.

Superflares of Sun-Like Stars

Astronomers have previously detected superflares from a variety of star types, which release bursts that have 10 to 10,000 times more energy than the largest solar flare ever detected from our sun. Scientists wanted to know how common these outbursts might be from stars like the sun, those with masses and temperatures similar to our star. Even normal solar flares can damage satellites, endanger astronauts and wreak havoc on electrical grids on Earth, suggesting that superflares might be catastrophic to life on Earth.

Monster Sunspot Fires is Unleashing Powerful Solar Flares

According to NASA scientists huge sunspot that dwarfs the Earth is unleashing a series of powerful solar flares as it moves across the surface of the sun. The sunspot AR 1476 was detected by space telescopes on May 5. The huge sunspot is 60,000 miles (100,000 kilometers) across, so large that when it was first seen in views from NASA’s Solar Dynamics Observatory spacecraft, mission scientists dubbed it a “monster sunspot.”

Sun Erupted in an Amazing Solar Flares

The sun erupted in an amazing solar flare on April 16, unleashing an intense eruption of super-heated plasma that arced high above the star’s surface before blasting out into space. The powerful solar flare occurred at 1:45 p.m. EDT (1745 GMT) and registered as a moderate M1.7-class on the scale of sun storms, placing it firmly in the middle of the scale used by scientists to measure flare strength. The storm is not the strongest this year from the sun, but photos and video of the solar flare captured by NASA spacecraft revealed it to be an eye-popping display of magnetic plasma.

Two More Solar Flares Erupted from the Sun on March 10

Two new solar flares erupted from the sun on March 10, blasting streams of plasma and charged particles into space. The outbursts were both categorized as M-class solar flares, and exploded from the surface of the sun at 12:27 a.m. EST(0527 GMT) and 12:44 p.m. EST (1744 GMT), respectively, according to NASA’s Goddard Space Flight Center in Greenbelt, Md.
These two flares came from the same Active Region (AR) on the sun, designated number 1429, that has already produced three X-class and numerous M-class flares over the past week.

Skywatchers Catch an Amazing Views of Auroras

Outbursts from the sun over the past week gave the best opportunity for skywatchers to catch an amazing views of auroras recently. The glowing auroras, also called the northern and southern lights, are caused when charged particles from the sun collide with Earth’s magnetic field. These charged particles are in abundance lately in the wake of a series of super-charged solar eruptions that began on March 6.

Powerful Solar Storm Triggered Weaker than Expected Disruptions

As scientists say powerful solar storm that slammed into Earth on March 8 triggered weaker than expected disruptions, but may still have a few more tricks up its sleeve. Two huge X-class solar flares that are the most powerful type of sun storm erupted from the sun late on March 6, hurling a wave of plasma and energetic particles toward Earth. This blast, called a coronal mass ejection, reached Earth at around 5:45 a.m. EST (1045 GMT) on March 8, according to officials at the Space Weather Prediction Center, which is jointly managed by the National Oceanic and Atmospheric Administration (NOAA) and the National Weather Service.

One of the Biggest Flare of the Solar Cycle

With the help of data from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) NASA models have now provided more information about the two CMEs associated with the two March 6 flares. The first is traveling faster than 1300 miles per second, the second more than 1100 miles per second. NASA’s models predict that the CMEs will impact both Earth and Mars, as well as pass by several NASA spacecraft, Messenger, Spitzer, and STEREO-B. The models also predict that the leading edge of the first CME will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours).
