[NZ4O Spaceweather] NZ4O Condensed HF Radiowave Propagation Forecast #2011-16

[Thomas F. Giella NZ4O]

The NZ4O Condensed HF Radiowave Propagation Forecast #2011-16 has been 
published at 0000 UTC on Friday April 22, 2011, valid 0000 UTC Saturday 
April 23, 2011 through 2359 UTC Friday April 28, 2011.
For a more in depth HF/6M frequency radiowave propagation go to section #3b 
and #4 of the NZ4O HF/6M Radiowave Propagation Forecast at 
http://www.solarcycle24.org  .

Note! This forecast is based upon quiet solar, space and geomagnetic weather 
conditions. Geomagnetic storming and energetic proton storms >10 MeV (10+0) 
can at times render the forecast inaccurate.
