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.
