Are Sunspots Disappearing (Forever)?

An interesting article appeared September 3, 2009 on the NASA Science web site asking this very question.

"Personally, I'm betting that sunspots are coming back," says researcher Matt Penn of the National Solar Observatory (NSO) in Tucson, Arizona. But, he allows, "there is some evidence that they won't."

"Sunspot magnetic fields are dropping by about 50 gauss per year," says Penn. "If we extrapolate this trend into the future, sunspots could completely vanish around the year 2015."

Check out this interesting article.
