The movie shows an eruption of unstable magnetic loops. The blast occured around 0130 UT on February 5th and may have hurled some material in the general direction of Earth. (Our planet is off the right edge of the image.) The Solar and Heliospheric Observatory (SOHO) has a direct view of the blast site and it may be able to help evaluate this possibility.
UPDATE: There is a gap in SOHO image data spanning the time of the eruption. At present, there is no sign of a major CME heading toward Earth, but a lesser cloud could be en route. Polar sky watchers should be alert for auroras on or about Feb. 8th.

in 1993 while high on LSD at the foot of MT Hood Oregon-my friend Vogel dropped the bomb that a bunch of exiled monks from Tibet were cackling about a solar flare coming in 2012 that was going to vaporize life on earth -start anew-i was FLOORED!
that is not something you tell someone very very high on psychedelics -that weekend was a long road trip to Autzen stadium in Eugene Oregon for the Grateful Dead-it took years to digest that download-i was very angry that i figured, back then and way before then that the governments of the world knew about this event yet said nothing to the masses(remember this was 1993)-i cried thinking/envisioning of mankind laying down arms going to family and friends and making amends and circling the planet hand in hand in robes of various colors stepping off into eternity together in the blink of an eye matter turning to light-now i don't if it was true, i hope its not true, i want to see my grandchildren on my lap... i do not know if we are going to make it that far-it seems like we have gone too far -big business has gained control-the armies of the world do their bidding-pollution is rampant and intentional...yet i hope and hope for my children that a Coronal Mass Ejection that size to cause extinction for us never happens-but let it come if the future is a dead planet by our hands-thy will be done

Die Free! The armies have always done their master's economic bidding. If this is all we are capable of, then so be it. |

More Active Sun Means Nasty Solar Storms Ahead

space.com – Wed Jun 9, 6:00 pm ET
The sun is about to get a lot more active, which could have ill effects on Earth. So to prepare, top sun scientists met Tuesday to discuss the best ways to protect Earth's satellites and other vital systems from the coming solar storms.
Solar storms occur when sunspots on our star erupt and spew out flumes of charged particles that can damage power systems. The sun's activity typically follows an 11-year cycle, and it looks to be coming out of a slump and gearing up for an active period.
"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity," said Richard Fisher, head of NASA's Heliophysics Division. "At the same time, our technological society has developed an unprecedented sensitivity to solar storms. The intersection of these two issues is what we're getting together to discuss."
Fisher and other experts met at the Space Weather Enterprise Forum, which took place in Washington, D.C., at the National Press Club.
Bad news for gizmos
People of the 21st century rely on high-tech systems for the basics of daily life. But smart power grids, GPS navigation, air travel, financial services and emergency radio communications can all be knocked out by intense solar activity.
A major solar storm could cause twenty times more economic damage than Hurricane Katrina, warned the National Academy of Sciences in a 2008 report, "Severe Space Weather Events—Societal and Economic Impacts." [Photos: Sun storms.]
Luckily, much of the damage can be mitigated if managers know a storm is coming. That's why better understanding of solar weather, and the ability to give advance warning, is especially important.
Putting satellites in 'safe mode' and disconnecting transformers can protect electronics from damaging electrical surges.
"Space weather forecasting is still in its infancy, but we're making rapid progress," said Thomas Bogdan, director of the National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center in Boulder, Colo.
Eyes on the sun
NASA and NOAA work together to manage a fleet of satellites that monitor the sun and help to predict its changes.
A pair of spacecraft called STEREO (Solar Terrestrial Relations Observatory) is stationed on opposite sides of the sun, offering a combined view of 90 percent of the solar surface. In addition, SDO (the Solar Dynamics Observatory), which just launched in February 2010, is able to photograph solar active regions with unprecedented spectral, temporal and spatial resolution. Also, an old satellite called the Advanced Composition Explorer (ACE), which launched in 1997, is still chugging along monitoring winds coming off the sun. And there are dozens more dedicated to solar science.
"I believe we're on the threshold of a new era in which space weather can be as influential in our daily lives as ordinary terrestrial weather." Fisher said. "We take this very seriously indeed." |

NASA: Solar storm to hit earth in 2013Mon, 21 Jun 2010 00:52:47 GMT
| Quote: |
NASA scientists predict a solar storm will hit the earth in 2013 mostly affecting electronic devices leading to a major catastrophe.
The once-in-a-generation storm, caused by extremely high levels magnetic energy released by solar flares, "will disrupt communication devices such as satellites and car navigations, air travel, the banking system, our computers, everything that is electronic," says Richard Fisher, head of NASA's Heliophysics Division, quoted in a June 14 Daily Telegraph article.
"Large areas will be without electricity power," says Fisher who emphasizes that the emergence of the storm is certain, though its degree of severity cannot be accurately foretold.
The National Academy of Sciences warned two years ago that a strong solar storm could cause "twenty times more economic damage than Hurricane Katrina," which devastated US Gulf of Mexico coastal city of New Orleans in 2005, killing thousands and living an estimated damage of over $125 billion.
According to Fisher, the storm, which will cause the sun to reach temperatures of more than 10,000 F (5,500 C), occurs "only a few times over a person's life."
Every 22 years, according to the report, the Sun's magnetic energy cycle reaches its highest level as the number sun spots - or flares - peaks every 11 years. These two events, says Fisher, "would combine in 2013 to produce huge levels of radiation."
In recent months, NASA's Solar Dynamics Observatory (SDO) has offered unique photos of sun spots, which release a vast amount of energy as they light up. |

Solar storm headed toward Earth may disrupt power
By SETH BORENSTEIN, AP Science Writer – 1 hour ago
| Quote: | WASHINGTON (AP) — The largest solar storm in five years is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and airplane flights.
The sun erupted Tuesday evening, and the effects should start smacking Earth between 1 a.m. and 5 a.m. EST Thursday, according to forecasters at the federal government's Space Weather Prediction Center. They say the storm, which started with a massive solar flare, is growing as it speeds outward from the sun.
"It's hitting us right in the nose," said Joe Kunches, a scientist for the National Oceanic and Atmospheric Administration. He called it the sun's version of "Super Tuesday."
Scientists say the sun has been relatively quiet for some time. And this storm, while strong, may seem fiercer because Earth has been lulled by several years of weak solar activity.
"This is a good-size event, but not the extreme type," said Bill Murtagh, program coordinator for the space weather center.
The solar storm is likely to last through Friday morning, but the region that erupted can still send more blasts our way, Kunches said. He said another set of active sunspots is ready to aim at Earth right after this.
But for now, scientists are waiting to see what happens Thursday when the charged particles hit Earth at 4 million mph.
NASA solar physicist Alex Young added, "It could give us a bit of a jolt." But he said this is far from a super solar storm.
The storm is coming after an earlier and weaker solar eruption happened Sunday, Kunches said. The latest blast of particles will probably arrive slightly later than forecasters first thought.
That means for North America the "good" part of a solar storm — the one that creates more noticeable auroras or Northern Lights — will peak Thursday evening. Auroras could dip as far south as the Great Lakes states or lower, Kunches said, but a full moon will make them harder to see.
Auroras are "probably the treat we get when the sun erupts," Kunches said.
But there is potential for widespread problems. Solar storms have three ways they can disrupt technology on Earth: with magnetic, radio and radiation emissions. This is an unusual situation when all three types of solar storm disruptions are likely to be strong, Kunches said.
That means "a whole host of things" could follow, he said.
The magnetic part of the storm has the potential to trip electrical power grids. Kunches said utility companies around the world have been alerted. The timing and speed of the storm determines whether it knocks off power grids, he said.
In 1989, a strong solar storm knocked out the power grid in Quebec, causing 6 million people to lose power.
Solar storms can also make global positioning systems less accurate, which is mostly a problem for precision drilling and other technologies, Kunches said. There also could be GPS outages.
The storm also can cause communication problems and added radiation around the north and south poles, which will probably force airlines to reroute flights. Some already have done so, Kunches said.
Satellites could be affected, too. NASA spokesman Rob Navias said the space agency isn't taking any extra precautions to protect astronauts on the International Space Station from added radiation.
