COMMENT: IPS SWF HF Communications Warning 10 was issued on 17 
February and is current for 17-18 Feb. Depressed HF conditions 
observed for Antarctic, Southern and some Northern AUS regions 
during local day and dusk, recovering overnight to be near monthly 
values. As the effects of recent geomagnetic/CME activity decline, 
MUF's are expected to range from near monthly predicted values 
to enhanced by 15% for both Northern and Southern AUS/NZ regions 
and mostly normal ionospheric support for Antarctic regions for 
the next 3 days. Further short-wave fadeouts are possible.
