COMMENT: Maximum usable frequencies (MUFs) ranged from near predicted 
monthly values to moderately enhanced during local night for 
Equatorial/Northern AUS and Southern AUS/NZ regions. Notable 
periods of degraded ionospheric support for Antarctic regions 
over the UT day. Similar HF conditions are expected for the next 
24 hours. Possible MUF depressions 10%-30% for Northern AUS and 
Southern AUS/NZ region and continued disturbed ionospheric support 
expected for 28May-29May due to increased geomagnetic activity.
