COMMENT: Minor to moderate degradations in HF conditions 
and MUF depressions may be observed across Aus/NZ regions 
for the next two to three days due to low ionisation in the 
ionosphere as the solar activity continues to remain at very 
low levels and also due to an expected continued rise in 
geomagnetic activity levels on 12 and 13 October.
