2. FORECAST (04 AUGUST - 06 AUGUST)
Date   T index  Conditions       MUFs                              
04 Aug     5    Normal           near predicted monthly values

                                 values    
COMMENT: HF conditions are expected to remain mostly normal in 
most parts of Aus/NZ regions for the next 1-2 days (04 to 05 
August). Onset of Unsettled geomagnetic activity from a recurrent 
coronal hole on 05-06 August (UT) will probably raise MUFs slightly. 
Very strong nightime spread-F was observed at low latitudes (DWN, 
LEA) and the reason is not readily apparent but maybe due to 
an inner magnetosphere disturbance observed yesterday on the 
GOES spacecraft.
