COMMENT: Mostly normal ionospheric support observed for Northern 
AUS and Southern AUS/NZ regions over the last 24 hours. Enhanced 
MUFs ~20% for Equatorial regions again. Poor ionospheric support 
for Antarctic regions due to the recent proton event. Continued 
enhanced conditions for Equatorial regions expected for the next 
2-3 days with mostly normal HF conditions for mid latitudes. 
Improving HF conditions expected for Antarctic regions over the 
next 24 hours with return to near monthly normal values.
