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.
