COMMENT: On 16-Jan, daytime MUFs were mildly to moderately depressed 
across Australia. Nightime MUFs were moderately to severely depressed 
across Australia, except in the Southern Australian Region where 
nightime MUFs were near predicted monthly values. Widespread 
sporadic-E was observed. Similar conditions are likely for the 
next 2 days, 17-Jan and 18-Jan. Depressions are expected to increase 
on 19-Jan due to increased geomagnetic activity which is forecast 
to start late 18-Jan. The current HF Communications Warning will 
be extended for 17-19 Jan.
