Date   T index  Conditions       MUFs                              
07 Feb   110    Normal           Near to 15% above predicted 
                                 monthly values
08 Feb   110    Normal           Near to 15% above predicted

COMMENT: Maximum usable frequencies (MUFs) in the Australian 
region on UT day 06-Feb were near predicted monthly values to 
25% enhanced. Sporadic E was observed throughout the Australian 
region. MUFs are expected to be near predicted monthly values 
to 15% enhanced over 07-09 Feb. There is a chance of degraded 
HF conditions over 07-08 Feb due to possible increased geomagnetic 
activity. Sporadic E is possible during local night, affecting 
lower frequencies.
