COMMENT: Notably depressed Maximum Usable Frequencies (MUFs) 
observed over Northern AUS/Equatorial regions for 24Oct and some 
periods of disturbed ionospheric support for Antarctic regions. 
MUF depressions of 30% possible for 25Oct-26Oct over Northern 
AUS and Southern AUS/NZ regions along with poor ionospheric support 
for Antarctic regions due to recent geomagnetic activity. Ionospheric 
recovery expected to commence 27Oct with MUFs at near predicted 
monthly values for Northern AUS and Southern AUS/NZ regions.
