2. FORECAST (24 MARCH - 26 MARCH)
Date   T index  Conditions       MUFs                              
24 Mar    90    Normal           Near predicted monthly values 
25 Mar   100    Normal           about 10% above predicted monthly 
                                 values     
26 Mar    75    Normal           about 10% below predicted monthly 
                                 values    
COMMENT: Continuing periods of geomagnetic disturbance have resulted 
in variable ionospheric depressions at low latitudes and extended 
localised periods of disturbance at high latitudes. An equatorial 
coronal hole is moving into geoeffective location and further 
ionospheric degradations are expected mid-week.
