Topband: VANISHING SUNSPOTS (http://spaceweather.com/)

Hi Kevin, 


Please share with us how you're begun to think that Cycle 24 will be 
looked at as the beginning of a new Maunder Minimum. 


Thanks

Thanks Bill. 

I think Cycle 24 will be looked at as the beginning of a new Maunder 
Minimum. 
If so then Cycle 24 will be as good as it gets for the next 70 years on 
the high bands.
