COMMENT: IPS HF Communications Warning 35 was issued on 14 October 
and is current for 15-16 Oct. MUF depressions of up to 25% during 
the local day were observed across the Australian region 15-Oct, 
as the ionosphere continues to recover from a series of small 
geomagnetic storms. Some minor MUF depressions are expected 16-Oct, 
predominantly during local day time, however ionospheric support 
is expected to steadily improve over the next three days.
