   Due to the Thanksgiving holiday tomorrow, the bulletin is coming out   
   two days early this week.  There is an overlap of one day on the   
   data reported at the end of the bulletin. Look for another bulletin   
   on Monday which will have more overlap, and Propagation Forecast   
   Bulletin ARLP049 a week from Friday will have still more overlap.   
   This is because the end of the bulletin always has seven days of   
   data, to keep it compatible with the Solar Data Plotting Utility   
   created by Scott Craig, WA4TTK. You can download the utility for   
   free at http://www.craigcentral.com/sol.asp. The Utility can handle   
   redundant data, but it must remain in a certain format in order for   
   it to glean data from the bulletin automatically.   
      
   Not much in the way of solar excitement this week, except there are   
   many sunspots, but the solar activity in terms of flares or coronal   
   mass ejections is low. The overlapping (by one day) average sunspot   
   numbers in this bulletin declined 21 points to 124   
      
   Expect good conditions for the CW weekend of the CQ Worldwide DX   
   Contest, November 26-27.   
      
   The latest prediction from USAF/NOAA shows solar flux at 140 on   
   November 23, 145 on November 24-27, 150 on November 28-29, 155 on   
   November 30, 160 December 1-2, and 165 December 3-7.  Predicted   
   planetary A index is 5 on November 23-27, 7 on November 28-29, then   
   5 on November 30 to December 24.

   18: "This whole week on forty meters during the Triple H Net on   
   7.190 at 0700 UTC I and others have been working central Australia   
   with strong 57 reports. Repeatedly I worked VK2NRB Bob and VK2TTP   
   Peter using just 100 watts and a wire dipole at 30 ft. each morning,   
   and also Europe is starting along with some Asia contacts. New   
   Zealand has been strong along with V21N in Antigua."
