2. FORECAST (21 MARCH - 23 MARCH)
Date   T index  Conditions       MUFs                              
21 Mar    65    Poor-normal      10 to 20% below predicted monthly 
                                 values 
22 Mar    90    Normal           Near predicted monthly values     
23 Mar   100    Normal           Near predicted monthly values    
COMMENT: As coronal hole wind stream effects persist into today, 
generally lower than normal MUFs are anticipated. Southern Aus/Antarctic 
regions can expect extended periods of disturbance in association 
with geomagnetic activity. Coronal hole wind stream effects are 
expected to decline after today. Short wave fadeouts are possible 
due to enhanced proton flux.
