HF conditions for Southern AUS/NZ regions. Disturbed conditions 
for Antarctic regions due to the increase in geomagnetic activity. 
MUF depressions of 10%-20% possible for low to mid latitudes 
for 30May-31May and continued disturbed conditions for Anarctic 
regions. A return to mostly normal HF conditions for all regions 
is expected on 01Jun.
