COMMENT: Mostly normal HF conditions were observed across the

mild MUF enhancements in Southern Australian and Antarctic regions. 
Mostly normal HF conditions may be expected in the Aus/NZ regions 
for the next three days (UT days 16 to 18 July) with the possibility 
of slight MUF depressions and degradations in HF conditions on 
UT day 16 July due to the possibility of slight rise in geomagnetic 
activity on this day.
