Mawson : no vertical MUF data or possible ionospheric absorption. ==================================================================== Note: autoscaled data is used to produce this report. Antarctic region autoscaled data can be inaccurate. Please check online ionograms to confirm conditions. MUFs within 15% of monthly predicted values are described as normal.
