2. FORECAST (11 FEBRUARY - 13 FEBRUARY)
Date   T index  Conditions       MUFs                              
11 Feb    50    Normal           Near predicted monthly values
12 Feb    55    Normal           Near predicted monthly values    
13 Feb    45    Normal-fair      Near predicted monthly values   

COMMENT: Observed MUF's for the UT day 10 Feb were near the predicted 
monthly values. The outlook (11 Feb) is for MUFs to remain near 
the monthly predicted levels. The solar ionising radiations (10.7 
cm solar flux) has been steady near 120 s.f.u for the last 7 
days. This is expected to maintain normal HF conditions. However, 
MUFs could degrade on UT day 13 Feb if there was active geomagnetic 
conditions associated with the coronal hole effects.
