For all of my amateur radio and SWL friends around the globe:
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.
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.
