   Solar flux and sunspot numbers moved in opposite directions over the past   
   week, and differences were more extreme than usual. Normally we expect daily   
   sunspot numbers and solar flux to track together, and geomagnetic indices to   
   track with each other as well, at least approximately.   
      
   Average daily sunspot numbers over the past reporting week (November 10-16)   
   rose 10 points from 18.7 to 28.7, while average daily solar flux dropped from   
   76.9 to 45.8. These comparisons express differences from the previous   
   reporting week, November 3-9.   
      
   Over the same dates average planetary A index increased markedly from 6.4 to   
   12.7, while the mid-latitude A index changed from 4.3 to 10.1.   
      
   Predicted solar flux values for the near future are 79 on November 18, 78 on   
   November 19, 80 on November 20-21, 78 on November 22-26, 80 on November 27, 82   
   on November 28 through December 1, 84 on   
   December 2, 82 on December 3-7, 80 on December 8-9, 78 on December 10, 75 on   
   December 11-15, 77 on December 16, 75 on December 17-21 and 78 on December   
   22-23.   
      
   The predicted planetary A index is 5, 16 and 18 on November 18-20, then 10,   
   48, 48, 36, and 28 on November 21-24, then 25, 18, 12, 10 and 8 on November   
   23-29, then 5 on November 30 til December 6, then 15, 12, 18, 20, 15 and 10 on   
   December 7-12 and 5 on December 13-15, then 10, 15, 55, 45, and 25 on December   
   16-20, then 18, 25, 18, 12, 10 and 8 on December 21-26, and 5 over the   
   following week.   
      
   http://www.spaceweather.com reports the solar cycle is currently at the lowest   
   level in 5 years.

   Thanks to Max White and David Moore for the above tip.   
      
      
   Petr Kolman, OK1MGW of the Czech Propagation Interest Group sent his   
   geomagnetic activity forecast for the period November 18 to December 14, 2016.   
      
   Geomagnetic field will be: Quiet on December 2-4, 13-14 Mostly quiet on   
   November 18, December 1, 12 Quiet to unsettled on November 19, 27-30, December   
   5-6, 11 Quiet to active on November 20, 24, December 7-10 Active to disturbed   
   on November 21-23, (25-26)   
      
   Amplifications of the solar wind from coronal holes are expected on November   
   20-26, December 7-10.   
      
   Parenthesis means lower probability of activity enhancement.   
      
      
   Jeff, N8II in West Virginia reports, "Saturday, November 12 I was able to work   
   24 each OK/OM Czech/Slovak stations on 15 meter CW (1352-1534Z) and 80 M in a   
   non-serious contest effort (with 100W).   
   On 15, I only worked one weak Slovak, but some Czechs were loud, very   
   selective! Sunday, the contest was over at 1200Z and the 15 M band did not   
   open east of Italy. I made the most QSOs on 20 with   
   good conditions, but central EU closes early with the time of year and low   
   SFI. 40 fades down quickly to EU after sunset.   
      
   "I just worked V63GW Micronesia with a good signal on 20M CW short path at   
   2032Z, expected him to be LP.   
      
   "Burma is now QRV and so far nil as expected in WV, best hope is 20 or 30M.   
      
   "Wednesday night, November 16 I worked ZD8W Ascension Island on 30 CW around   
   0100Z with S5-7 signal.   
      
   "Thursday 15 M was open as far north as northern Germany (Hanover) and I   
   easily broke a EU pile up on FR4QF on Reunion Island on 15 SSB at 1522Z; he   
   was peaking S9."

   Sunspot numbers for November 10 through 16 were 13, 26, 51, 38, 26, 29, and   
   18, with a mean of 28.7. 10.7 cm flux was 80.2, 78.4, 78.4, 77.8, 77.3, 76.5,
