2. FORECAST (31 JANUARY - 02 FEBRUARY)
Date   T index  Conditions       MUFs                              
31 Jan    75    Normal           Near predicted monthly values
01 Feb    75    Normal           Near predicted monthly values    
02 Feb    75    Normal           Near predicted monthly values   

COMMENT: MUFs were mostly near predicted monthly values but enhanced 
near equatorial latitudes. MUFs are expected to be possibly slightly 
suppressed to near monthly averages on 31 Jan due to Unsettled 
geomagnetic conditions and then remain at that level for the 
following 2 days due to the lower number of sunspots and ionising 
EUV. Antarctic region MUFs may be more significantly suppressed 
than mid latitudes on 31 Jan due to the geomagnetic disturbance 
which will reach Active levels.
