2. FORECAST (11 JUNE - 13 JUNE)
Date   T index  Conditions       MUFs                              
11 Jun    85    Normal           Near predicted monthly values 
                                 to 15% enhanced
12 Jun    80    Normal-fair      Near predicted monthly values    
13 Jun    70    Normal-fair      Near predicted monthly values 
                                 to 15% depressed   

COMMENT: Maximum usable frequencies (MUFs) in the Australian 
region were near predicted values on UT day 10-Jun. Sporadic-E 
was observed in Learmonth and Canberra overnight and spread-F 
in Hobart. MUFs are expected to be near predicted values to 15% 
enhanced on 11-Jun, but trending to near predicted values on 
12-Jun and up to 15% depressed by 13-Jun due to anticipated geomagnetic 
activity from a coronal hole.
