2. FORECAST (15 AUGUST - 17 AUGUST)
Date   T index  Conditions       MUFs                              
15 Aug    60    Normal           Near predicted monthly values
16 Aug    60    Normal           Near predicted monthly values    
17 Aug    45    Fair             Depressed 15%/near predicted 
                                 monthly values   

COMMENT: Maximum usable frequencies (MUFs) on UT day 14-Aug were 
mostly near predicted monthly values, with mildly depressed conditions 
in the Northern Australian region during local night. Spread-F 
was observed at Hobart during local night. MUFs are expected 
to be mostly near predicted monthly values over 15-16 Aug. Mildly 
degraded conditions are possible for the southern Australian 
region from 17-Aug due to the expected arrival of CMEs first 
observed on 13-Aug and 14-Aug combined with the effects of an 
equatorial coronal hole high speed wind stream.
