COMMENT: Mostly normal HF conditions were observed across the 
Aus/NZ regions today (UT day 13 July) with periods of minor to 
mild MUF enhancements in the Southern Australian and Antarctic 
regions. Strong sporadic E layers were observed during late hours 
of the local day in Australian regions. Mostly normal HF conditions 
may be expected in the Aus/NZ regions for the next three days 
(UT days 14 to 16 July) with the possibility of some MUF depressions 
and degradations in HF conditions on UT day 16 July due to the 
possibility of some rise in geomagnetic activity on this day 
(UT day 16 July).
