2. FORECAST (14 MARCH - 16 MARCH)
Date   T index  Conditions       MUFs                              
14 Mar   120    Normal           15 to 20% above predicted monthly 
                                 values
15 Mar   100    Normal-fair      Near predicted monthly values    
16 Mar   100    Fair             About 15% below predicted monthly 
                                 values   

COMMENT: Maximum usable frequencies (MUFs) on UT day 13-Mar were 
20-40% enhanced in the Australian region. MUFs are expected to 
be 15-20% enhanced on 14-Mar, and near monthly values over 15-16 
Mar due to an anticipated mild increase in geomagnetic activity 
over 14-15 Mar. Stronger geomagnetic activity is likely from 
mid 15-Mar from a more recent CME, and depressed ionospheric 
conditions may follow on 16-Mar for the southern Australian region.
