2. FORECAST (17 OCTOBER - 19 OCTOBER)
Date   T index  Conditions       MUFs                              
17 Oct    80    Normal           Near predicted monthly values
18 Oct    80    Normal-fair      Near predicted monthly values    
19 Oct    80    Normal           Near predicted monthly values   

COMMENT: MUFs recovered to near predicted monthly values as the 
ionosphere recovered from a series of small geomagnetic storms 
earlier in the week, assisted by EUV flux from numerous spot 
groups now on the solar disc. Minor MUF depressions may occur 
17-Oct as Earth may pass through a narrow high speed solar wind 
speed stream from a coronal hole rotating into geoeffective longitude 
on the solar disc, causing geomagnetic disturbances.
