COMMENT: Some MUF depressions were observed across the Aus/NZ 
regions over the last 24 hours possibly due to weak ionisation 
as the solar activity has stayed at very low levels for several 
days. Further depressions in MUFs may be expected on 28 and 29 
November due to expected rise in geomagnetic activity on these 
days and due to continued very low solar activity levels. Minor 
to mild depressions in MUFs may be possible on 30 November due 
to the expectation of solar activity to continue to stay at very 
low levels until then.
