2. FORECAST (04 MARCH - 06 MARCH)
Date   T index  Conditions       MUFs                              
04 Mar   115    Normal           Near predicted monthly values 
                                 to 15% enhanced
05 Mar   100    Normal-fair      Near predicted monthly values 
                                 to 15% enhanced    
06 Mar    90    Normal-fair      Depressed 10 to 15%/near predicted 
                                 monthly values   

COMMENT: Maximum usable frequencies (MUFs) were mostly 20-30% 
enhanced in the northern Australian region, with strongly enhanced 
MUFs observed at Niue. Southern Australian region MUFs were depressed 
15% during the local day. Mild spread-F was observed at Perth 
and Hobart during local night hours. Southern Australian region 
MUFs are depressed 15% after local dawn but these current mildly 
depressed conditions are not expected to persist. MUFs are generally 
expected to be near predicted monthly values to 10-15% enhanced 
over 04-05 Mar, and becoming 15% depressed to near predicted 
monthly values in the southern Australian region on 06-Mar due 
to anticipated mild geomagnetic activity from a coronal hole 
wind stream.
