COMMENT: Expect minor MUF depressions in the in the Equatorial 
and north Australian Regions due to low ionisation in the ionosphere 
resulting from very low solar activity. The geomagntic activity 
on 4 and 5 September is not expected to affect south Australia 
or Antarctic HF conditions, other than a slight degradation in 
HF propagation.
