Where are all the sunspots?

The Sun currently emits less radio noise THAN AT ANY POINT SINCE 1955. The solar wind pressure is currently LOWER THAN AT ANY OTHER RECORDED TIME (NASA first kept track in the 1960's). More galactic cosmic rays (GCRs) bombard the Earth now THAN AT ANY OTHER RECORDED TIME (due to the low solar wind pressure). This means you're soaking up an extra dose of GCRs if you fly in an airplane or live at a very high altitude. Satellites are currently experiencing less atmospheric drag than normal, resulting in greater orbital stability with less fuel expended for station-keeping. Since 2004, we've had 602 sunspot-free days. The typical Solar Minimum lasts for 485 days. 91 days in 2009 have been sunspot-free
