COMMENT: Conditions for HF radio wave propagation were near predicted 
monthly values throughout the Australian region during 5 Jul. 
These conditions were enhanced relative to the previous week, 
a positive effect of the G2 class geomagnetic storm occurring 
during 4-5 Jul. The conditions were more strongly enhanced at 
midlatitude stations. For example, preliminary T indices were 
102 at Brisbane and 65 at Cocos Island. Similar conditions are 
expected today, 6 Jul, though trending back toward mildly depressed, 
especially at low latitude stations.
