Darwin : near normal Hobart : no vertical MUF data or possible blanketing sporadic E. Learmonth : near normal Niue Is : near normal Norfolk Is : near normal Perth : near normal Sydney : no vertical MUF data. Townsville : near normal ========================================================================================= Antarctic Station Vertical Maximum Usable Frequencies (MUFs) - average over last 4 hours ========================================================================================= Casey : depressed by -16% Davis : no vertical MUF data or possible ionospheric absorption. 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.
