      Alex or anyone:

      HamCAP apparently wants the 90-day smoothed sunspot number in the
      Parameters screen. I can't seem to find that on any of the NOAA
      databases. Is it the same as the projected number on the following
      graph for the current month? It's not clear to me what period they
      are smoothing over for this graph.

      http://www.sel.noaa.gov/ftpdir/weekly/sunspot.gif

      If I am interpolating correctly, the current smoothed SSN is about 20.
      Is that the correct number to input to HamCAP?

      73, Bill W4ZV
