Date   T index  Conditions       MUFs                              
09 Jan    70    Fair-normal      Depressed 10 to 15%/near predicted 
                                 monthly values

COMMENT: Maximum usable frequencies (MUFs) in the Australian 
region were enhanced by 15-25% over UT day 08-Jan, with values 
trending towards predicted monthly values during local night 
hours and accompanied by some Sporadic-E. Spread F was also observed 
during local night hours in the southern Australian region. MUFs 
were near predicted monthly values in the Antarctic region. MUFs 
are forecast to become depressed relative to current values over 
09-11 Jan, with depressions of 10-15% forecast due to geomagnetic 
activity. Isolated shortwave fadeouts are possible, and sporadic-E 
may be observed during local night hours.
