Quietest Sun since 1913
"Owen Duffy" wrote in message ... Peter, Your reference is interesting, their story is changing from http://science.nasa.gov/headlines/y2...cleupdate.htm? list174385 (fix the wrapped URL). I have been plotting the percentage of days in a calendar month that were spotless during this transition. Certainly, March 2009 isn't encouraging. The graphs are at http://www.vk1od.net/propagation/solar/spotless.htm . I wouldn't hazard a guess at when sunspot numbers climb significantly, though signs are that the transition has already occured, just enduring a very long sunspot drought... from Canberra where it doesn't rain any more either!
