ionospheric support for Equatorial regions and poor conditions 
for Antarctic regions. Similar conditions are expected for the 
next 24 hours. Chance of possible isolated enhancements as well 
as MUF depressions of ~30% for Northern AUS and Southern AUS/NZ 
regions and disturbed ionospheric support for Antarctic regions 
from mid way through the UT day on 31Jan. Depressed MUFs for 
low to mid latitude stations and disturbed ionospheric support 
for high latitudes expected on 01Feb due to increased geomagnetic 
activity.
