I'm sure you have all heard of this but I would like to hear more insight from people who know more then me.

NASA Magnetic Field Breach

Do some signs seem to point to pole shift / geomagnetic reversal? Or will the Earth's magnetic field bounce back from this?

The Sun can now rip open the magnetosphere, what the heck? Anyone have any updates on this?

Curses! How ever did the Rebels manage to pass through the surprise party that was waiting for them on Endor?

Basicaly what this looks like here is that there is a large reconnection event taking place at the magnetopause, the outer reaches of the magnetosphere in the direction of the sun. However, the problem is that reconnection can only happen if there is "oppositely" directed magnetic fields, and the solar wind had the same polarity as the Earth. This would mean that there cannot be any reconnection, and thus no entry of particles into the magnetosphere.

I would have to see the paper, I might have missed the presentation this week at the AGU meeting. But what I can imagine happening is that the reconnection starts at high latitudes first and then there is a development down. But that is just speculation and should be taken with lots of salt.

This has nothing to do with field reversal and no the Earth's magnetic field is not disappearing.

Unfortunately, there is no mention of where this will be published, so I guess we have to wait.

This page:

http://www.nasa.gov/mission_pages/th...ky_shield.html

appears to have some clues on what has and what will be published.

First:

Emphasis added. I assume this is the article that they're referring to:

THEMIS multi-spacecraft observations of magnetosheath plasma penetration deep into the dayside low-latitude magnetosphere for northward and strong By IMF


And later in the NASA article it says:

Again, emphasis added. So, Li's article on the simulation will be published in the Journal of Geophysical Research.

if it wasn't so cold and snowy outside, i think i might go outside and run around waving my hands in the air like a madman, since this is obviously one of the first signs of the end of the world.

Nah, I think the stock market beat it this time around, but that's probably due to insider trading.

Greetings,

I have been using the following link to follow the sun's weather--it is fairly well-done:

Thanks van Rijn. I downloaded the paper (I have a subscription to GRL and JGR) and will look through the paper. More info later.

Will have to search for the Li paper.

Okay, a quick look at the abstract shows that there was a significant By in the solar wind (i.e. in the direction of Earth's motion around the sun) and thus it would be fairly "easy" to get component reconnection on the magnetopause. So, it is not so surprising, the surprising thing is that in the press release it was so emphasized that it was strongly northward, but then ey! it's a press release, and you should know by now what my opinion of press releases is ...

well, lucky me.. the coldness and snowiness prevented me from getting outdoors, so no one ran outside and waved their arms frantically...

So it is only the principles in this investigation that are agog?

Hey motion creates emotion. Nothing wrong with a bit of hand waving and romping in the snow. You go novaderrick! Darn the torpedos!

Wondering out-loud:

Notice the dramatic drop in solar wind density downstream. Could this mean that the solar wind actually adds atmosphere to the earth, rather than stripping it away?

It is well known that solar wind plasma enters the magnetosphere during reconnection events.

I would think our gravity is enough to lessen atmo loss. More than Mars at least.
