ESA's Cluster spacecraft were in the right place at the right time on September 15, 2001. They flew through a region of the Earth's magnetosphere at the exact moment that it reconfigured itself. The wealth of data will help scientists better model interactions between the Earth's magnetosphere and the solar wind, as well as the magnetic fields around other stars and exotic objects with powerful magnetic fields.

An abstract and arXiv e-print can be found here (http://arxiv.org/abs/physics/0606014), where the authors mention that the evidence is consistent with a magnetic reconnection event, not that they have definitively observed one.

The most important line in the news release:

We don't know whether reconnection events, if that is what this is, are rare or common.

My personal favourite is:


Xiao and his colleagues used the Cluster data to deduce the three-dimensional structure and size of the null point, revealing a surprise.

The null point exists in an unexpected vortex structure about 500 kilometres across. “This characteristic size has never been reported before in observations, theory or simulations,” say Xiao, Pu and Wang.

My bold, Vortex structure???? As if in helical twist?? What takes on this characteristic shape in the universe??? Mmmmm....surprising if you were just expecting magical magnetic reconection taking place!!!

Also lots of magnetic "stuff" appearing in seeming isolation to any asociated electrical "stuff". Question is can this realy be the case? :whistle:
