HF Radiowave Propagation Forecast Valid 1200 UTC Saturday April 23, 2011
through 1200 UTC Sunday April 24, 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.
