The NZ4O MF/HF/6M (600-6 Meters) Radiowave Propagation Forecast #2012-18 has been published at 0000 UTC on Friday April 27, 2012, valid 0000 UTC Saturday April 28, 2012 through 2359 UTC Friday May 04, 2012.

This condensed forecast can also be found on Facebook at http://www.facebook.com/pages/SolarCycle24org/139198369462931

The complete MF/HF/6M forecast can be found at http://www.solarcycle24.org and http://www.wcflunatall.com/propagation.htm .

Note! This forecast is based upon quiet solar, space and geomagnetic weather conditions. Geomagnetic storming Kp-5> and energetic proton storms >10 MeV (10+0) can at times render the forecast temporarily inaccurate.
