february 5 2008 _ yellow magnetic star [ix ka]
On the 15th of February 2001, NASA published this article, communicating that there had been a reversal in the magnetic poles of the sun. It was the solar maxima of the 23rd solar cycle and the magnetic north turned to face south. Solar cycles last for 11 years and are accompanied by spots that appear on the sun, starting with one at the beginning of the cycle, and increasing in number when the solar cycle reaches its maximum. These spots appear in the middle of the cycle and then shrink to a new minimum, giving way to a new cycle.
In the same way, the magnetic fields of the earth reverse. The last time they inverted was approximately 740,000 years ago. Some scientists believe that we should have already experienced a new reversal, but they are unsure of when it will happen. The reversal can occur in intervals that range from 5.000 to 50.000.000 years. Although the magnetic fields of the sun and the earth behave in different ways, what they have in common is their structure. We explained in our article Fractal Universe that this structure is a Toroidal shaped domain.
The magnetic field of the sun, this Donut shape or Toroid, envelops the whole of our solar system into a bubble that scientists call the Heliosphere. Outside of the interstellar space, it is easy to understand the rotation of our planet if we understand that the sun also rotates, once every 27,2 days (see image). The magnetic fields that surround the sun intertwine, forming spirals that impact with our planet making it turn on itself. We are strongly linked to the sun.
On the 10th of January we received this new from NASA, announcing the start of the 24th solar cycle with the first sunspot of inverted polarity. This new cycle will last until 2019 and will peak in 2012, when the magnetic north pole of the sun will stop facing south and turn to face north again. The period when the sun is at its maximum will last for 2 years, and cause potent electrical storms on earth, affecting our planet, and having a detrimental effect on technology.
Four days later, on the 14th of January we received one more article from NASA. They told us about the satellite Ulysses, that has been studying the sun for the last 10 years,and that at this important point of the cycle, it's beginning, is flying over the sun's north pole. Each time Ulysses has orbited over the poles, it has revealed important information, but scientists believe that this solar cycle will offer a spectacle different to other years, due to some anomalies that have been detected in the behaviour of the high speed polar winds.
How this will affect the earth's magnetic fields, is something that we don’t know, but it promises to be interesting and different. We will keep you informed.For further information :
