2. FORECAST (27 JANUARY - 29 JANUARY)
Date   T index  Conditions       MUFs                              
27 Jan   115    Normal           Near to 15% above predicted 
                                 monthly values
28 Jan   115    Normal           Near to 15% above predicted 
                                 monthly values    
29 Jan   125    Normal           Near to 15% above predicted 
                                 monthly values   

COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
and Antarctic regions were near predicted monthly values to 20% 
enhanced, with up to 50% enhancements seen in the Northern Australia 
region during local night. Seasonal sporadic-E was observed in 
the Southern Australian region, with strong sporadic-E reported 
in the Cocos Islands. Spread F was also observed in Hobart. MUFs 
are expected to be near predicted monthly values to 15% enhanced 
over 27-29 Jan, with geomagnetic activity from a small coronal 
hole high speed wind stream likely to prevent further enhancements 
over this period. Sporadic-E may be observed during local night 
hours.
