Date   T index  Conditions       MUFs                              
08 May    55    Normal-fair      Depressed 10 to 15%/near predicted 
                                 monthly values
09 May    60    Normal           Near predicted monthly values    
10 May    65    Normal           Near predicted monthly values   

COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
region were largely near predicted values during daylight hours 
on UT day 07-May, with depressions of up to 15% reported during 
local night hours. MUFs are forecast to continue to have depressions 
of 10-15% on 08-May due to coronal hole high speed wind stream 
effects. MUFs are then expected to improve over 09-10 May as 
this geomagnetic activity subsides. Shortwave fadeouts are possible 
over 09-10 May.
