2. FORECAST (15 OCTOBER - 17 OCTOBER)
Date   T index  Conditions       MUFs                              
15 Oct    20    Normal           about 5% below predicted monthly 
                                 values 
16 Oct    15    Normal           5 to 10% below predicted monthly 
                                 values     
17 Oct    15    Normal           5 to 10% below predicted monthly 
                                 values    
COMMENT: MUFs at mid and low latitudes continued to be slow recovering 
from the CME induced geomagnetic disturbance on the 12th. Recovery 
to slightly monthly values should be helped by low geomagnetic 
activity and three active regions on the solar disc with more 
ionising radiation. Another CME may strike a glancing blow during 
local day on the 15th with possible ionospheric depressions.
