writes "August 2008 has made solar history. As of 00 UTC September 1st 2008 (5PM PST)
we just witnessed the
first spotless calendar month since June 1913.This was determined according
data from NOAA's National Geophysical Data Center, which goes back to 1749.
In the 95 years since 1913, we've had quite an active sun, but activity has been
declining in the last few years.
The sun today is a nearly featureless sphere and has been spotless for 42
days total, but this is the first full calendar month since 1913 for a spotless
sun. And there are other indicators of the sun being in a funk. Australia's
space weather agency recently revised their solar cycle 24 forecast, pushing the
expected date for a ramping up of
cycle 24 sunspots into the future by six months."Link to Original Source
