2. FORECAST (03 SEPTEMBER - 05 SEPTEMBER)
Date   T index  Conditions       MUFs                              
03 Sep    80    Normal-fair      Near predicted monthly values

05 Sep    70    Normal           Near predicted monthly values   

COMMENT: MUFs are at near predicted values across Australia. 
On day 1 (3rd Sep UT) geomagnetic activity may cause reduction 
in MUFs in the later half of the UT day, particularly in southern 
regions. Some depressed periods are expected for central and 
southern regions on day 2, improving on day 3. Depressions are 
expected to be relatively mild with MUFs near predicted monthly 
values for most of the time. There is a downside risk if the 
geomagnetic activity is more intense than expected, so periods 
of more significant depressions are possible, particularly on 
day 2.
