COMMENT: Conditions ranged from near predicted monthly values 
for Southern AUS/NZ regions to slightly depressed MUF's for Northern 
AUS/Equatorial regions during local day for 24Oct. Increased 
geomagnetic activity over the next 3 days is expected to result 
in notable MUF depressions for Northern AUS and Southern AUS/NZ 
regions over this time. Poor ionospheric support for Antarctic 
regions expected during this period.
