Geomagnetic Storm Watch - Sun's magnetic field near Earth tipped South - early hours Dec 28, 2010
GEO-STORM WATCH: A geomagnetic storm is brewing. The sun's magnetic field near Earth tipped south during the early hours of Dec. 28th, opening a crack in Earth's magnetosphere. Solar wind pouring in could spark bright Northern Lights around the Arctic Circle. High-latitude sky watchers should be alert for auroras.

Dec. 3, 2003:Â Earth is surrounded by a magnetic force field--a bubble in space called "the magnetosphere" tens of thousands of miles wide. Although many people don't know it exists, the magnetosphere is familiar. It's a far flung part of the same planetary magnetic field that deflects compass needles here on Earth's surface. And it's important. The magnetosphere acts as a shield that protects us from solar storms.
According to new observations, however, from NASA's IMAGE spacecraft and the joint NASA/European Space Agency Cluster satellites, immense cracks sometimes develop in Earth's magnetosphere and remain open for hours. This allows the solar wind to gush through and power stormy space weather... http://science.nasa.gov/science-news/science-at-nasa/2003/03dec_magneticcracks/

Incoming from Space News: 'So bright it was frightening': Dazzling meteor 'fireball' hurtles through the skies above Britain
http://www.dailymail.co.uk/sciencetech/article-1337110/Dazzlingly-bright-meteor-hurtles-skies-Britain.htmlNOTE: Would this be classified over the United States given the following from 2009 ???????
Military Hush-Up: Incoming Space Rocks Now Classified
By Leonard David
SPACE.com's Space Insider Columnist
posted: 10 June 2009
05:35 pm ET
For 15 years, scientists have benefited from data gleaned by U.S. classified satellites of natural fireball events in Earth's atmosphere – but no longer.
A recent U.S. military policy decision now explicitly states that observations by hush-hush government spacecraft of incoming bolides and fireballs are classified secret and are not to be released, SPACE.com has learned.
The satellites' main objectives include detecting nuclear bomb tests, and their characterizations of asteroids and lesser meteoroids as they crash through the atmosphere has been a byproduct data bonanza for scientists.
The upshot: Space rocks that explode in the atmosphere are now classified.
"It's baffling to us why this would suddenly change," said one scientist familiar with the work. "It's unfortunate because there was this great synergy...a very good cooperative arrangement. Systems were put into dual-use mode where a lot of science was getting done that couldn't be done any other way. It's a regrettable change in policy."
Scientists say not only will research into the threat from space be hampered, but public understanding of sometimes dramatic sky explosions will be diminished, perhaps leading to hype and fear of the unknown.
Incoming!
Most "shooting stars" are caused by natural space debris no larger than peas. But routinely, rocks as big as basketballs and even small cars crash into the atmosphere. Most vaporize or explode on the way in, but some reach the surface or explode above the surface. Understandably, scientists want to know about these events so they can better predict the risk here on Earth.
Yet because the world is two-thirds ocean, most incoming objects aren't visible to observers on the ground. Many other incoming space rocks go unnoticed because daylight drowns them out.
Over the last decade or so, hundreds of these events have been spotted by the classified satellites. Priceless observational information derived from the spacecraft were made quickly available, giving researchers such insights as time, a location, height above the surface, as well as light-curves to help pin down the amount of energy churned out from the fireballs.
And in the shaky world we now live, it's nice to know that a sky-high detonation is natural versus a nuclear weapon blast.
Where the space-based surveillance truly shines is over remote stretches of ocean – far away from the prospect of ground-based data collection.
But all that ended within the last few months, leaving scientists blind-sided and miffed by the shift in policy. The hope is that the policy decision will be revisited and overturned.
Critical importance
"The fireball data from military or surveillance assets have been of critical importance for assessing the impact hazard," said David Morrison, a Near Earth Object (NEO) scientist at NASA's Ames Research Center. He noted that his views are his own, not as a NASA spokesperson.
The size of the average largest atmospheric impact from small asteroids is a key piece of experimental data to anchor the low-energy end of the power-law distribution of impactors, from asteroids greater than 6 miles (10 kilometers) in diameter down to the meter scale, Morrison told SPACE.com.
"These fireball data together with astronomical observations of larger near-Earth asteroids define the nature of the impact hazard and allow rational planning to deal with this issue," Morrison said.
Morrison said that fireball data are today playing additional important roles.
As example, the fireball data together with infrasound allowed scientists to verify the approximate size and energy of the unique Carancas impact in the Altiplano -- on the Peru-Bolivia border -- on Sept. 15, 2007.
Fireball information also played an important part in the story of the small asteroid 2008 TC3, Morrison said. That was the first-ever case of the astronomical detection of a small asteroid before it hit last year. The fireball data were key for locating the impact point and the subsequent recovery of fragments from this impact.
Link in public understanding
Astronomers are closing in on a years-long effort to find most of the potentially devastating large asteroids in our neck of the cosmic woods, those that could cause widespread regional or global devastation. Now they plan to look for the smaller stuff.
So it is ironic that the availability of these fireball data should be curtailed just at the time the NEO program is moving toward surveying the small impactors that are most likely to be picked up in the fireball monitoring program, Morrision said.
"These data have been available to the scientific community for the past decade," he said. "It is unfortunate this information is shut off just when it is becoming more valuable to the community interested in characterizing near Earth asteroids and protecting our planet from asteroid impacts."
The newly issued policy edict by the U.S. military of reporting fireball observations from satellites also caught the attention of Clark Chapman, a planetary scientist and asteroid impact expert at Southwest Research Institute in Boulder, Colorado.
"I think that this information is very important to make public," Chapman told SPACE.com.
"More important than the scientific value, I think, is that these rare, bright fireballs provide a link in public understanding to the asteroid impact hazard posed by still larger and less frequent asteroids," Chapman explained.
Those objects are witnessed by unsuspecting people in far-flung places, Chapman said, often generating incorrect and exaggerated reports.
"The grounding achieved by associating these reports by untrained observers with the satellite measurements is very useful for calibrating the observer reports and closing the loop with folks who think they have seen something mysterious and extraordinary," Chapman said.

EPIC Solar Blast - December 6, 2010
EPIC BLAST: As predicted, the a "mega-filament" of solar magnetism erupted on Dec. 6th, producing a blast of epic proportions. NASA's Solar Dynamics Observatory recorded the action as the 700,000-km long structure lifted off the stellar surface and--snap!!--hurled itself into space. Click on the arrow to play the movie:
movie formats: 4 MB gif, 1 MB iPad, 0.5 MB iPhone, 1 MB still frame
The eruption produced a bright coronal mass ejection (CME) observed by the STEREO-A spacecraft: video. Earth was not in the line of fire; the cloud should sail wide of our planet. Earth-effects might be limited to pretty pictures.

Spaceweather.com | 2 CMEs observed by SOHO on Friday November 26, 2010
FARSIDE ACTIVITY: The far side of the sun is alive with activity. On Nov. 26th, NASA's twin STEREO spacecraft and the Solar and Heliospheric Observatory (SOHO) observed two farside coronal mass ejections (CMEs) billowing into space. The first one came from old sunspot 1126, located just over the sun's southwestern horizon.
Hours later, a second CME followed, but not from the same blast site. The second CME came from an active region near the sun's anti-Earth point, almost directly opposite our planet on the solar farside. If Earth were on the other side of the sun, we would be be expecting bright auroras from the impact of these clouds. Instead, the alert is for "all quiet." Nothing major is heading our way.
The farside active regions that produced these eruptions will turn to face Earth in 7 to 14 days.
