Scientists Predict Big Sunspot Cycle Coming
Boulder CO (SPX) March 6, 2006
Solar scientists said Monday the next sunspot cycle could be 30 percent to 50 percent stronger than the last one, and it could begin up to a year later than expected – although other scientists dispute the timing prediction.
Scientists using a new computer model at the National Center for Atmospheric Research said they now understand what drives the Sun's 11-year cycle of sunspot activity, and they are confident the model can help them predict the cycle accurately enough to allow NASA and the satellite and electric-power industries prepare for periods of maximum solar magnetic activity years in advance.
The peak of the cycle, called the Solar Maximum, generates more frequent magnetic storms and ejections of energetic particles that can slow satellite orbits - thereby interfering with global navigation – as well as disrupt communications and bring down power systems.

Scientists are Starting to Understand Solar Cycles
Mon, 06 Mar 2006 - Solar scientists think they're finally getting a handle on predicting the Sun's cycles. If everything goes as they predict, the next solar cycle will be 30-50% stronger, and be up to a year late. Astronomers have been tracking the two major flows of plasma that goven the Sun's cycles. One acts like a conveyor belt, pulling plasma from the poles to the equator, and the other gets stretched since the Sun rotates faster at the equator than at the poles. This causes the Sun's magnetic field to concentrate, creating the solar maximum.
Scientists predict the next solar activity cycle will be 30 to 50 percent stronger than the previous one and up to a year late. Accurately predicting the sun's cycles will help plan for the effects of solar storms. The storms can disrupt satellite orbits and electronics; interfere with radio communication; damage power systems; and can be hazardous to unprotected astronauts.

Considering calm right now we are experiencing on the Sun, and the lack of sunspot activity...maybe are are in for a blast!...
