Australian Region conditions at: 1900 UT 07/09/25 Station Vertical Maximum Usable Frequencies (MUFs) - average over last 2 hours ===================================================================================== Brisbane : near normal Canberra : near normal Cocos Is : no vertical MUF data. Darwin : depressed by -18% Hobart : near normal 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 : enhanced by 20% Davis : no vertical MUF data or possible ionospheric absorption. Mawson : near normal ==================================================================== 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.
