COMMENT: IPS HF Communications Warning 35 was issued on 14 October 
and is current for 15-16 Oct. MUF depressions of up to 30% during 
the local day were observed across the Australian region 14-Oct, 
as the ionosphere continues to recover from a series of small 
geomagnetic storms. Ongoing moderate MUF depressions and some 
degraded HF conditions are expected 15-Oct, predominantly during 
local day time, with a gradual strengthening of the ionosphere 
over the next few days.
