COMMENT: Local daytime and evening MUF depressions of 20% observed 
over Northern AUS and Southern AUS/NZ regions during the last 
24 hours, and mostly normal HF conditions for local nights. Antarctic 
regions experienced mostly normal HF conditions with isolated 
enhanced periods. Continued sporadic E observed for Southern 
AUS/NZ regions. This pattern of ionospheric behaviour is expected 
to continue for the next 2 days while solar and geomagnetic activity 
remain at very low levels. Chance of disturbed ionospheric conditions 
for polar regions in the next 2 days due to transient effects 
from recent CME's.
