COMMENT: The Australian ionosphere was mostly normal over the 
UT day. MUFs were near predicted monthly values. HF conditions 
were fair-normal with the exception of the Antarctic region which 
saw some significant degradation as a result of enhanced high 
latitude activity. Range Spread-F was again observed in the S.Aus/NZ 
region overnight as well as isolated sporadic-E at mid-latitudes. 
Expect mostly normal HF conditions with MUFs near predicted monthly 
values 19 Jun, and continuing poor ionospheric support in Antarctic 
regions.
