Date   T index  Conditions       MUFs

COMMENT: The Australian ionosphere was mostly normal over the 
UT day. MUFs were near predicted monthly values or slightly enhanced 
(overnight). HF conditions were mostly normal with the exception 
of the Antarctic region which saw some significant degradation 
of HF conditions resulting from enhanced high latitude activity. 
Some range Spread-F was observed in the S.Aus/NZ region overnight. 
Expect mostly normal HF conditions and MUFs near predicted monthly 
values 17 Jun. Some minor depressions possible 18-19 Jun and 
continuing poor ionospheric support in Antarctic regions.
