Date   T index  Conditions       MUFs                              
03 Aug   130    Normal           Near predicted monthly values 
                                 to 15% enhanced.
04 Aug   130    Normal-fair      Near predicted monthly values

05 Aug   130    Normal-fair      Near predicted monthly values 
                                 to 15% enhanced.   

COMMENT: Maximum usable frequencies (MUFs) on UT day 02-Aug were 
near predicted values to 15% enhanced in the Australian region. 
A shortwave fadeout was observed 02/0425-0819UT impacting lower 
HF frequencies. Spread F was observed at Hobart and Perth during 
local night hours. Scintillation was observed at Niue 02/0829-0910UT. 
MUFs are expected to be near predicted monthly values to 15% 
enhanced. Mildly degraded HF conditions may be experienced during 
local night hours 04-05 Aug for the southern Australian region. 
Shortwave fadeouts are probable.
