Also, I think everyone now agrees that Venus has no internal magnetic field and the whole magnetosphere is created by draped field lines from the solar wind. There could be slight surface anomalies just like at Mars, but that will be all (although the surface temperature of Venus may be above the Curie point, destroying any anomalies). In a couple of months the periapsis of VEX will be lowered and we will get even closer to the surface.

While visiting at NCAR in Boulder I spent some time looking at their body of geomagnetic data, for purchase. They gave me a "catalog of geomagnetic data" book to order from, and a sample book of one year of published charts, graphs, and tables of the data, (several years old) to show me the printed format it was available in.
When I got it home I proceeded to plot out all of the interesting times when there were large disturbances in the global fields. What was apparent from the plotting was the times when the moon or the Earth passed thru the other's magnetosphere's tail,the turbulence of the interaction of the two was felt at the surface of the Earth.
I also found a paper that showed during a total solar eclipse the Ionosphere's E and F layers rebounded to almost their normal night time height.
It is this I was referring to about the Moon and Earth being intrinsically linked. (not locked) The quotes I found in the original EU thread post were sniped out of the original Hypothesis I had posted to my first web site that was later lost, due to hard drive failure.
