COMMENT: Depressed MUF's during local night for Northern AUS/Equatorial 
regions observed over the last 24 hours. Enhanced conditions 
for Southern AUS/NZ regions during local night. Either disturbed 
HF conditions or enhanced periods for Antarctic regions. GOES 
satellite indicates a decline in x-ray flux levels which may 
see average MUF's decline and T indicies fall below monthly averages 
over the next few days. MUF depressions of 10%-20% expected for 
Northern AUS/Equatorial regions and possibly for Southern AUS/NZ 
regions for the next 3 days with otherwise normal ionospheric 
support.
