There's a huge thread on glp on the magnetosphere. Lots of data and information- not the typical glp thread if you kwim. Quite fascinating and something is definitely going on there. I've been following that thread since it started...between the magnetosphere, the sun's strange activity lately and a neutron star emitting gamma ray bursts directly at us right now there is something huge going on 'up there'. Meanwhile our magnetosphere is breached and not protecting us as it normally does.
We live in such amazing times. There's so much going on and it's all related imo, all of it. From TPTB's actions to climate/earth changes to 2012.

Yes... I don't doubt that we may have picked the short straw as being "on shift" as the great cosmos orientates to the flat alignment - the ancients described a sky we thought was just fanciful hooey... but when you look at the recent activities of the scientific crowd and the obvious signs of change... I have no doubt we will be privy to the sights and sounds of the ancient sky's - again.

Earth's Core, Magnetic Field Changing Fast, Study Says

Global Research, July 13, 2008 National Geographic News
Rapid changes in the churning movement of Earth's liquid outer core are weakening the magnetic field in some regions of the planet's surface, a new study says.
"What is so surprising is that rapid, almost sudden, changes take place in the Earth's magnetic field," said study co-author Nils Olsen, a geophysicist at the Danish National Space Center in Copenhagen.
The findings suggest similarly quick changes are simultaneously occurring in the liquid metal, 1,900 miles (3,000 kilometers) below the surface, he said.
The swirling flow of molten iron and nickel around Earth's solid center triggers an electrical current, which generates the planet's magnetic field.

The study, published recently in Nature Geoscience, modeled Earth's magnetic field using nine years of highly accurate satellite data.
Fluctuations in the magnetic field have occurred in several far-flung regions of Earth, the researchers found.
In 2003 scientists found pronounced changes in the magnetic field in the Australasian region. In 2004, however, the changes were focused on Southern Africa.
The changes "may suggest the possibility of an upcoming reversal of the geomagnetic field," said study co-author Mioara Mandea, a scientist at the German Research Centre for Geosciences in Potsdam.
Earth's magnetic field has reversed hundreds of times over the past billion years, and the process could take thousands of years to complete.

Upper Atmosphere Radiation
The decline in the magnetic field also is opening Earth's upper atmosphere to intense charged particle radiation, scientists say.
Satellite data show the geomagnetic field decreasing in the South Atlantic region, Mandea said, adding that an oval-shaped area east of Brazil is significantly weaker than similar latitudes in other parts of the world.
"It is in this region that the shielding effect of the magnetic field is severely reduced, thus allowing high energy particles of the hard radiation belt to penetrate deep into the upper atmosphere to altitudes below a hundred kilometers (62 miles)," Mandea said.
This radiation does not influence temperatures on Earth. The particles, however, do affect technical and radio equipment and can damage electronic equipment on satellites and airplanes, Olsen of the Danish space center said.
The study documents just how rapidly the flow in Earth's core is changing, said Peter Olson, a geophysics professor at Johns Hopkins University in Baltimore, Maryland, who was not involved with the research.
By using satellite imagery, researchers have a nearly continuous measurement of changes, he said.
"They provide a good rationale to continue this monitoring longer," Olson said.

Large Holes Found in Earth's Magnetic Shield
Published 16 May 2009. Irene Klotz
Freelance writer for the American Geophysical Union
It is not just the size and the strength of solar storms that threaten power grids, disable satellites, and scramble radio signals on Earth; it’s also the fact that large holes can form in Earth's protective magnetosphere—even during what were presumed to be periods of peaceful coalignments of solar and terrestrial magnetic fields.
Scientists had thought that when the Sun's magnetic field was aligned with Earth's, the planet was safely cocooned within its protective bubble because Earth's magnetic field would deflect the electrically charged particles streaming from the Sun, similar to the way two magnets repel each other when their poles are aligned.
Observations from NASA's Time History of Events and Macroscale Interactions During Substorms (THEMIS) satellite network, however, show otherwise.
