COMMENT: MUF depressions of ~20% observed during local night 
for Northern AUS/Equatorial and Southern AUS/NZ regions over 
the last 24 hours. Notable sporadic E for Northern AUS regions 
and some Southern AUS IPS stations between 09-13UT. Mostly normal 
HF conditions for Antarctic regions with occasional depressed 
periods. Similar ionospheric support is expected for the next 
3 days, with MUF depressions of 10%-20% for the low to mid latitudes. 
Possible increase in geomagnetic activity over the next 24-48 
hours could result in disturbed conditions for mid to high latitudes 
for 04Dec-05Dec.
