An excerpt from the latest ARRL Propagation Bulletin:
--------------
"Another great resource is the NOAA Space Environment Center's
Preliminary Report and forecast, which comes out weekly. It used to
be published on paper and mailed, but you can look at it in PDF form
at the SEC NOAA we site at,
http://www.sec.noaa.gov/weekly/index.html .
The current issue, published May 6, has some tables showing
predicted solar flux and sunspot numbers until the end of 2007, and
smoothed numbers back to January 1998."
---------------
The latest issue is indeed a pretty interesting document.
Page 18 is worth printing and hanging on the wall of the shack.
It predicts solar flux values in the 70's from January 2005
through December 2007. It shows that the monthly smoothed
values have fallen from about 238 to 125 in about 18 months.
