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.”
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.
NASA’s Solar Dynamics Observatory spacecraft has captured video of a massive solar tornado five times wider than the Earth twisting its way across the surface of the sun. As said researchers NASA’s Solar Dynamics Observatory (SDO) looked on as the huge, swirling storm raged on Sept. 25, 2011, spinning solar gas at speeds up to 186,000 mph (300,000 kph. Here on Earth, tornado wind speeds top out at around 300 mph (483 kph).
According to Nasa scientists a recent spate of furious eruptions on the surface of the sun hurled a huge amount of heat toward Earth. This is the biggest dose our planet has received from our closest star in seven years. Although the influx of solar energy puffed up the atmosphere, increasing drag on low-orbiting satellites, it caused fewer disruptions to electronic infrastructure such as electronic grids than some expected.
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.
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.
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.
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).
Sun unleashed five solar eruptions in only two days last week. The solar storms flared up between February 23 and 24 and exploded from nearly all areas of the star, including the top, bottom, left and right sides of the solar disk as seen by space-based observatories, according to NASA scientists. In fact, four of these outbursts came within a single 24-hour period. One of the eruptions churned out an impressive magnetic filament in the early hours of February 24. This triggered the first of two coronal mass ejections (CMEs) that were blasted toward Earth.
