2. FORECAST (07 JANUARY - 09 JANUARY)
Date   T index  Conditions       MUFs                              
07 Jan   105    Normal           Near to 15% above predicted 
                                 monthly values
08 Jan   105    Normal           Near to 15% above predicted 
                                 monthly values    
09 Jan    90    Normal-fair      Near predicted monthly values   

COMMENT: Maximum usable frequencies (MUFs) were enhanced 15-20% 
compared with predicted monthly values during UT day 06-Jan, 
in the Northern Australian region. MUFs were mostly near predicted 
monthly values in the Southern Australian region. Sporadic-E 
was observed across the Australian region during local night 
hours, with mild spread F observed in Canberra, Perth, Brisbane 
and Townsville during local night. MUFs are forecast to remain 
enhanced over the 07-08 Jan. MUFs will likely decline to near 
predicted monthly values on the 09-Jan, due to anticipated geomagnetic 
activity. Shortwave fadeouts are possible, and sporadic-E may 
be observed during local night hours.
