COMMENT: On the UT day 8 January in the Australian region MUFs 
were depressed by 15% - 20% during local day and after local 
dawn as a result of the recent increase in the geomagnetic activity 
and mostly near monthly predicted values during local night. 
On 9-10 January similar HF conditions are expected, with MUFs 
gradually recovering. HF users are advised to use lower than 
the monthly predicted frequencies.
