Space storm tracked from sun to earth

(PhysOrg.com) -- For the first time, a spacecraft far from Earth has turned and watched a solar storm engulf our planet. The movie, released today during a NASA press conference, has galvanized solar physicists, who say it could lead to important advances in space weather forecasting.

"The movie sent chills down my spine," says Craig DeForest of the Southwest Researcher Institute in Boulder, Colorado. "It shows a CME swelling into an enormous wall of plasma and then washing over the tiny blue speck of Earth where we live. I felt very small."

CMEs are billion-ton clouds of solar plasma launched by the same explosions that spark solar flares. When they sweep past our planet, they can cause auroras, radiation storms, and in extreme cases power outages. Tracking these clouds and predicting their arrival is an important part of space weather forecasting.

"We have seen CMEs before, but never quite like this," says Lika Guhathakurta, program scientist for the STEREO mission at NASA headquarters. "STEREO-A has given us a new view of solar storms."

NASA's STEREO spacecraft and new data processing techniques have succeeded in tracking space weather events from their origin in the sun's corona to impact with the Earth, resolving a 40-year mystery about the structure of the structures that cause space weather: how the structures that impact the Earth relate to the corresponding structures in the solar corona.

STEREO-A is one of two spacecraft launched in 2006 to observe solar activity from widely-spaced locations. At the time of the storm, STEREO-A was more than 65 million miles from Earth, giving it the "big picture" view other spacecraft in Earth orbit lack.

When CMEs first leave the sun, they are bright and easy to see. Visibility is quickly reduced, however, as the clouds expand into the void. By the time a typical CME crosses the orbit of Venus, it is a billion times fainter than the surface of the full Moon, and more than a thousand times fainter than the Milky Way. CMEs that reach Earth are almost as gossamer as vacuum itself and correspondingly transparent.

"Pulling these faint clouds out of the confusion of starlight and interplanetary dust has been an enormous challenge," says DeForest.

Indeed, it took almost three years for his team to learn how to do it. Footage of the storm released today was recorded back in December 2008, and they have been working on it ever since. Now that the technique has been perfected, it can be applied on a regular basis without such a long delay.

Alysha Reinard of NOAA's Space Weather Prediction Center explains the benefits for space weather forecasting:

"Until quite recently, spacecraft could see CMEs only when they were still quite close to the sun. By calculating a CME's speed during this brief period, we were able to estimate when it would reach Earth. After the first few hours, however, the CME would leave this field of view and after that we were 'in the dark' about its progress."

"The ability to track a cloud continuously from the Sun to Earth is a big improvement," she continues. "In the past, our very best predictions of CME arrival times had uncertainties of plus or minus 4 hours," she continues. "The kind of movies we've seen today could significantly reduce the error bars."

The movies pinpoint not only the arrival time of the CME, but also its mass. From the brightness of the cloud, researchers can calculate the gas density with impressive precision. Their results for the Dec. 2008 event agreed with actual in situ measurements at the few percent level. When this technique is applied to future storms, forecasters will be able to estimate its impact with greater confidence.

At the press conference, DeForest pointed out some of the movie's highlights: When the CME first left the sun, it was cavernous, with walls of magnetism encircling a cloud of low-density gas. As the CME crossed the Sun-Earth divide, however, its shape changed. The CME "snow-plowed" through the solar wind, scooping up material to form a towering wall of plasma. By the time the CME reached Earth, its forward wall was sagging inward under the weight of accumulated gas.

The kind of magnetic transformations revealed by the movie deeply impressed Guhathakurta: "I have always thought that in heliophysics understanding the magnetic field is equivalent to the 'dark energy' problem of astrophysics. Often, we cannot see the magnetic field, yet it orchestrates almost everything. These images from STEREO give us a real sense of what the underlying magnetic field is doing."

All of the speakers at today's press event stressed that the images go beyond the understanding of a single event. The inner physics of CMEs have been laid bare for the first time -- a development that will profoundly shape theoretical models and computer-generated forecasts of CMEs for many years to come.

"This is what the STEREO mission was launched to do," concludes Guhathakurta, "and it is terrific to see it live up to that promise."

There is nothing low about finally admitting that Earth's climate is influenced by the violently unstable neutron star remnant of a supernova that gave birth to the solar system five billion years (5 Gyr) ago.

Here are some of the data and observations:

Delusions of that sort are new for you Oliver. The paper did no such thing. However did show that Sun is very active which goes against the crap you were posting a few weeks ago where it was predicted that the Sun should be going inactive.

Here are some of the data and observations:
There is some of the usual crap that has no evidence supporting it.

And IF the Sun created the metals in the Solar System via a supernova THEN the metals would be in the outer Solar System as well since Super Nova blast matter out for LIGHT YEARS around and are not magically restricted to the inner Solar System.

Consensus science is Big Brothers tool to control people and information. World leaders secretly formed BB to protect the world (themselves) from the threat of mutual nuclear annihilation.

That noble goal cannot be achieved in democratic societies by deception.

It is encouraging that Australian citizens are uniting in convoys headed to Canberra for a show of no confidence in government leaders support for the AGW story and the environmentalist movement [1].

Since world leaders and leaders of scientific organizations and the news media apparently secretly united about 40 years ago to support environmentalism and AGW (anthropogenic global climate change) propaganda of the day,

Citizens of the world must now unite in demanding an end to tyranny and restoration of the basic right of citizens to control their governments.

Ah yes instead of answering relevant question Oliver makes another wild rant. A man who lived a lie is ranting that other are liars. Mainly because science has rejected his unsupported inanity.

Do support yourself someday Oliver. Surely you must be able to produce something in the way of evidence. After all if you can't then any competent honest scientist would admit that his idea was wrong.

Go back to reality paedo your soapboxing for metal sun is just wasting your time and making us laugh at you. On topic have to say that video is very beutifull and shows a very gloriouse and beutifull part of the cosmos for us all to see.

This is the best type of science to me. It demonstrates something and shows it in a way that the layman can see and understand as well as fowarding human understanding.

Historically political power is linked with ability to predict climate change.

1. Joseph was in prison with no political power when he correctly forecast seven years of plenty followed by seven years of drought and famine in Egypt [1]. He thus became politically powerful.

2. Al Gore was politically powerful when he forecast AGW. He lost by ignoring deceit in Climategate e-mails [2], thus revealing a) Validity of Eisenhowers 1961 warning of the danger of a federal scientific-technological elite [3], and b) Offstage agreements to save us from nuclear annihilation [4] in 1971 when I was a PI in NASAs Apollo program.

3. I became an opponent of the deal and AGW dogma by reporting the origin, composition and unstable source of energy in the Earth-Sun system [5 and references there].

CONCLUSION: Government decisions based on ignorance caused todays economic, social and political unrest [e.g., 6].

"political power is linked with ability to predict climate change."

So are you saying since you have little political power you also have little ability to predict climate change?

Horseshit as usual. People made predictions BEFORE any government was involved except as a general source of funding for research. Same as you used to get.

Joseph was in prison with no political power
Or any actual existence. Its a story Oliver. Possibly based on a real person but that person would have working for the Hixos.

2. Al Gore was politically powerful when he forecast AGW.
He didn't forecast it. He publicized it.

He lost by ignoring deceit in Climategate e-mails
He lost it by losing to Bush in the Election. There is no sign of actual deceit in the e-mails. Just normal behavior by researchers with differences of opinion.

Translation. He didn't like being ignored for promoting a theory that doesn't the evidence.

Government decisions based on ignorance caused todays economic, social and political unrest
The conclusion may be true but is not related to the crap that preceded it. Indeed much of it was NOT ignorance. It was idiotology from Right Wingers.

Thing that Oliver won't answer but must if he is to return to being a scientist instead of a Crank.

What evidence, real evidence not wild assed speculation based on your theory, is there for the Sun having a neutron star within it and and iron mantle so near the surface you claim we can see it in Sun Spots? Keep in mind that the Sun Spots do NOT have large amounts of iron. Indeed they have the traces expected by standard theory.

Please produce evidence that bound neutrons decay.
