The Sun's Odd Behavior

gyrogeerloose writes "Most of us know about the sun's eleven-year activity cycle. However, relatively few other than scientists (and amateur radio operators) are aware that the current solar minimum has lasted much longer than expected. The last solar cycle, Cycle 24, bottomed out in 2008, and Cycle 25 should be well on its way towards maximum by now, but the sun has remained unusually quiescent with very few sunspots. While solar physicists agree that this is odd, the explanation remains elusive."

Enough data?

[fenring]

I almost know nothing on the subject, but I'm thinking the 11 year cycle was empiricaly determined. One has to wonder do we have enough data on the subject compared to the age of the sun?
