COMMENT: Mostly normal HF conditions observed during the last 
24 hours. Northern AUS/Equatorial regions experienced depressed 
MUFs during local day. Southern AUS/NZ regions had continued 
enhanced conditions during local night. Mostly normal conditions 
for Antarctic regions with enhancements over the UT day. These 
regional ionospheric conditions are expected to remain unchanged 
for the next 24 hours, but with an anticiapted increase in geomagnetic 
activity over the next 2 days, MUF depressions ~20% are possible 
for Northern AUS and Southern AUS/NZ regions and disturbed ionospheric 
conditions for Antarctic regions.
