2. FORECAST (07 FEBRUARY - 09 FEBRUARY)
Date   T index  Conditions       MUFs                              
07 Feb    45    Normal           depressed 10 to 15%/near predicted 
                                 monthly values 
08 Feb    70    Normal           Near predicted monthly values     
09 Feb    70    Normal           Near predicted monthly values    
COMMENT: Mild/moderate depressions probable briefly after local 
dawn for southern Aus/NZ regions today, then near predicted monthly 
values. Depression appears to be ionsospheric response to mild 
geomagentic activity induced by unexpected southward interplanetary 
magnetic field (IMF) conditions. The IMF is now neutral therefore 
depressed MUF conditions are not expected to persist.
