COMMENT: Mostly normal HF conditions observed during the last 
24 hours. Both Northern AUS and Southern AUS/NZ regions experienced 
depressed MUFs during local day. Northern AUS and Equatorial 
regions experienced disturbed conditions between 1600-2100UT 
while there was enhanced ionospheric support for Southern AUS/NZ 
regions during local night. Continued disturbed conditions for 
Antarctic regions. Similar HF conditions are expected over the 
next 2 days. An expected increase in geomagnetic activity on 
09Jul could bring possible MUF depressions ~20% for Southern 
AUS/NZ and Antarctic regions.
