From NASA:

"September 3, 2009: The sun is in the pits of the deepest solar minimum in nearly a century. Weeks and sometimes whole months go by without even a single tiny sunspot. The quiet has dragged out for more than two years, prompting some observers to wonder, are sunspots disappearing?"

"'Personally, I'm betting that sunspots are coming back,' says researcher Matt Penn of the National Solar Observatory (NSO) in Tucson, Arizona. But, he allows, 'there is some evidence that they won't.'"

The NASA press release is covered in more detail at but an earlier post about their 2nd (and successful) attempt at publishing is more useful, see

Of the many interesting things going on the sun at the moment, this is the most fascinating and I think should receive much wider attention.
