A MONTH WITHOUT SUNSPOTS: The sun has just passed an entire calendar month with no sunspots. The last time this happened, in August 2008, the sun was in the nadir of a century-class Solar Minimum. The current stretch of blank suns shows that Solar Minimum has returned, and it could be as deep as the last one. Visit Spaceweather.com for more information and current sunspot counts.
