COMMENT: Variable ionospheric support observed over the last 
24 hours with depressed MUF's observed for Southern AUS/NZ regions 
and some Northern AUS/Equatorial regions. Disturbed conditions 
for some Antarctic stations. Continued elevated geomagnetic activity 
expected for 19Feb should see variable ionospheric support, with 
possible MUF depressions of ~20% for Southern AUS/NZ regions 
and disturbed ionospheric conditions for Antarctic regions. Possible 
enhanced periods during local day for low-latitude/equatorial 
regions. Ionospheric recovery is expected from 20Feb onwards.
