Date   T index  Conditions       MUFs                              
28 Nov    55    Fair-normal      Depressed 10 to 15%/near predicted 
                                 monthly values

COMMENT: Maximum usable frequencies (MUFs) on UT day 27-Nov were 
generally near predicted monthly values. Spread F was observed 
at Hobart, and southern region MUFs are depressed about 15% after 
local dawn this morning. MUFs are expected to be mildly depressed 
to near predicted monthly values for 28-Nov, and near predicted 
monthly values for 29-30 Nov. Degraded HF conditions may be experienced 
during local night hours on 30-Nov and on 01-Dec for the southern 
Australian region in association with anticipated geomagnetic 
activity induced by a solar coronal hole wind stream.
