2. FORECAST (08 JANUARY - 10 JANUARY)
Date   T index  Conditions       MUFs                              
08 Jan   105    Normal           10 to 20% above predicted monthly 
                                 values
09 Jan    80    Fair-normal      Depressed 10 to 15% /near predicted 
                                 monthly values    
10 Jan    80    Fair-normal      Depressed 10 to 15% /near predicted 
                                 monthly values   

COMMENT: Maximum useable frequencies (MUFs) in the Australian 
region were enhanced by 15-20% during UT day 07-Jan, with enhancements 
of up to 30% reported in the Northern Australian region. The 
Antarctic and Niue Island regions were near predicted monthly 
values. Strong sporadic-E affected mid- and polar latitudes during 
local night hours. 10-20% enhancements in MUFs are expected on 
08-Jan, then declining to be 10% depressed during 09-10 Jan due 
to coronal hole high-speed wind stream effects. Sporadic-E is 
possible during local night hours. Shortwave fadeouts are possible.
