Sun Unleashes “Massive Solar Flares” in One-Two Punch

Just as many Americans got back to work after the long Labor Day weekend, the sun jolted to life as well, unleashing a massive solar flare just one day after another sun storm sent a stream of particles racing toward Earth.

The X-class solar flare — the most powerful type of sun storm— erupted at 6:12 p.m. EDT (2212 GMT) on Tuesday (Sept. 6) and hit its peak strength eight minutes later, according to a space weather update by the National Oceanic and Atmospheric Administration (NOAA). The flare occurred less than 24 hours after another less intense but still dramatic solar storm.

Several different satellites watched the action unfold, including NASA’s Solar Dynamics Observatory, which constantly records high-definition videos of the sun in several different wavelengths. [Photo of the X-class solar flare]

The Tuesday event registered as an X2.1-class solar flare, while Monday’s storm topped out at a still-powerful M5, NOAA officials said. Strong solar flares are classified according to a three-tiered system: X-class flares are the most powerful, M-class are of medium strength and C-class are the weakest.

September solar storms

Researchers are still taking the measure of the big Tuesday sun storm. It may also have produced a coronal mass ejection (CME) aimed at Earth, researchers said, but as of Tuesday evening it was too early to tell.

CMEs are massive clouds of solar plasma that can streak through space at up to 3 million mph (5 million kph). CMEs that hit Earth can wreak havoc on our planet, causing disruptions in GPS signals, radio communications and power grids. [Sun’s Wrath: Worst Solar Storms in History]

Monday’s event, which took place at 9:50 p.m. EDT (0150 GMT on Tuesday), did spawn a CME. It was a relatively slow one, traveling at less than 720,000 mph (1.2 million kph), NASA officials said. And even if this cloud of charged particles hits Earth in a few days’ time, it likely won’t cause much damage.

“This CME is not expected to cause significant geomagnetic storm activity, and further analysis is currently underway to better refine the CME timing and magnitude,” officials at NOAA’s Space Weather Prediction Center wrote in an update Tuesday.

Monday’s M5 solar flare erupted from the middle of the sun’s disk as seen from Earth’s perspective. The explosion caused a slight increase in solar energetic protons about 26,000 miles (41,840 kilometers) above the Earth’s surface, NASA officials said.

The angry sun

The powerful storms unleashed on Monday and Tuesday aren’t isolated incidents. Solar activity has been ramping up over the last few months as the sun has roused itself from an extended quiescent phase in its 11-year activity cycle.

Just last month, for example, the sun let loose with an X6.9 solar flare, which was the most powerful solar storm since December 2006, NASA scientists said. That storm, which erupted Aug. 9, also generated a CME, but it was not aimed at Earth. Another powerful event, an X2.2-class flare, occurred on Feb. 15 of this year. Tuesday’s X2.1 was the third most powerful flare of 2011.

Scientists expect activity in the current cycle — known as Solar Cycle 24 — to peak around 2013.

    Read well and study on your own after you have read this.

    This is not a game or joke our Sun gives off a Solar Wind all day year round if you live in the State of Alaska you see it in the sky above what a sight it is going through our Earth’s Magnet Polls of the North and the South, North Poll. Its Called the Northern Lights or the Aurora Borealis.

    The day will come when you will be able to see it all over Earth as in the year 1859 Solar Flare. Two Astronomer’s Hodgson and Carrington told the World that the Solar Flare made a Geomagnetic Storm reach Earth in hours not days. Back then it gave new meaning to Reach For The Skies from Telegraph Operators. For hours sparks flew from the key board. Even after the Batteries were disconnected.

    Our Sun’s UV Rays will get stronger as each passing day go’s by, read and i will tell you why.

    The Great big forest have be striped from most of the Earth for Greed of Money by the Wicked. The trees our are Main Source of Oxygen on this Plant.
    The Forest Trees scrubs the Pollution out of the air and makes Oxygen from the rain and dirt that it grows in.

    The Forest Trees do more then just make Oxygen they stop Soil Erosion, just Look at the 1930 Dust Bowl. Greed by our Government taxes led farmers to clear cut all their Forest and farm all the land they were being Tax on. They had to farm it to pay for the Taxes. Why leave the Trees when food crop makes Money. This Did not Help the Depression that effected most all Worldwide.

    The Pollution and CO2 Carbon Dioxide go into the Tree Bark as a shield from most bugs so they do not eat the tree.

    Less Forest less Oxygen this is why the moon. That has no Oxygen is very cold on the side with out Sun Light,And hot as ever on the side with Sun Light. Way too cold and too hot to live there.

    With no blank of Oxygen to lessen or reduce the Sun’s UV Rays and Solar Wind they are deadly there on our Moon. Every Mt. Climber and Aircraft Pilot knows the higher you go the thinner the Oxygen and colder it gets.

    Just spend a night on a Mt. top above 13,000 feet with no Sun Light and you will see or should i say feel the cold stinging any of your exposed skin. If you are new to Mt. Climbing stay below 10,000Ft. The Astronauts and the Cosmonauts and Fighter Pilots that i have been with for years know this very well, and the Radiation Hazards to humans at High Altitudes.

    Soon the Sun’s Solar Wind and UV rays will be way to strong for most to go out in the Sun Light for even a short time. The Geomagnetic Storm to come and the Bad Weather Storms well you have not seen nothing yet and the Sea Level is Rising the Oceans.

    The last 30 years On Earth we have broke all high temp records and the temp it is still going up. All the Worlds Ice Glacier are melting at an Accelerating Rate. The Glaciers and Polar Ice Caps store more water than all the Fresh Water Lakes on Earth.

    The Bad Weather Storms now are Babies compared to what is to come.

    They will get even bigger and worse less Oxygen the more UV Rays to the Earth and more Water molecules will evaporate and go up into the Earth’s Atmosphere. Less Oxygen the colder with out sun light and hotter with it.

    The Sky full of more water vapor molecules, more snow in the winter and more Flash Floods in the Summer.

    If every living person on Earth were to Plant A Tree Today we might have a chance.

    The Earth’s Atmosphere Blanket surrounding it protects life on Earth as Our Lord and GOD will all that seek Him.

    Then it is written when the tree is full it is harvest time. All the Earth will someday burn away.

    This is all Foretold in the Bible Read it
    and may our Lord Bless all that do so.

    The Lord’s Little Helper

    P.S.
    2 Peter 3:10
    But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the Earth and its works will be burned up.
