The sun is in the pits of a very deep solar minimum. Many researchers thought the sunspot cycle had hit bottom in 2008 when the sun was blank 73% of the time. Not so. 2009 is on the verge of going even lower. So far this year, the sun has been blank 75% of the time, and only a serious outbreak of sunspots over the next few weeks will prevent 2009 from becoming the quietest year in a century.
