05 March 2005 | The latest research results[1] by Drs. Leif Svalgaard, Yohsuke Kamide at the Solar-Terrestrial Environment Laboratory, Nagoya University (Japan) and Edward W. Cliver at the Space Vehicles Directorate, Air Force Research Laboratory, Hanscom Air Force Base (Massachusetts) suggest that the Sun may be less active during the next solar cycle than it has been during the last 100 years.
These results are based upon one of the most successful solar cycle prediction methods in existence. The "Precursor Method" is capable of predicting the magnitude of the next solar maximum up to about 7 years before the solar maximum occurs. This is possible by examining the strength of the magnetic fields that congregate in the polar regions of the Sun a few years before the solar minimum of each solar cycle and relating the strength of those fields to the observed sunspot numbers during the next solar maximum. The polar magnetic fields provide the "seed" magnetic flux necessary to drive the sunspot activity during the next solar cycle.
