values to enhanced over all AUS/NZ regions over the last 24 hours

activity. Possible enhancements followed by expected MUF depressions 
for Northern AUS to Southern AUS/NZ regions and disturbed ionospheric 
support for Antarctic regions for 07May followed by mildly depressed 
MUFs for Northern AUS to Southern AUS/NZ regions and disturbed 
ionospheric support for Antarctic regions for 08May-09May.
