COMMENT: Maximum usable frequencies (MUFs) on UT day 13-Jun were 
near predicted monthly values to 15% depressed in the Australian 
region, particularly during local night hours. Spread-F was observed 
in Hobart and Brisbane during local night hours. MUFs are expected 
to be near predicted values over 14-15 Jun, but may become depressed 
by 16-Jun due to possible anticipated geomagnetic activity. Shortwave 
fadeouts are possible.
