What is a Saros? Quoting Wikipedia:
‘One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur’

‘It takes between 1226 and 1550 years for the members of a saros series to traverse the Earth’s surface from north to south (or vice-versa)’

Only a few lines to go … (more…)

Our friend Vukevic called by and gave me a pointer to a links page at his site which provides a resource for those interested in studying planetary, solar and magnetic phenomena.

Here’s an example demonstrating the match between the sunspot number and Vuk’s planetary motion derived formulas:

Hopefully, Vuk will call back to give us some further info on his research.

Here’s another interesting correlation. The Position of the north magnetic pole has been shifting rapidly over the last several decades. The rate of change of it’s declination correlates with the variations in Earth’s length of day and the motion of the sun relative to the centre of mass of the solar system which we discussed in my first post.

North Pole rate of change of declination vs LOD vs SSBz

More interesting information on Earth’s magnetism and it’s relationship with the sun here: http://www.appinsys.com/GlobalWarming/EarthMagneticField.htm

If the changes in Length of Day are related to changes in the circulation of currents of molten material beneath the Earth’s crust, we could speculate that magnetic  iron ores are shifting their predominant accumulations and this affects the location of the magnetic north pole.
