Deep Solar Minimum


    Where have all the sunspots gone? The sun has been blank on 85% of the days of 2009. If this rate of spotlessness continues through the end of the year, 2009 will match 1913 as the blankest year of the past century. A flurry of new-cycle sunspots in Oct. 2008 prompted some observers to declare that solar minimum was ending, but since then the calm has returned. We are still in the pits of a deep solar minimum. []
