COMMENT: Notable depressed MUFs observed for Northern AUS, Southern 
AUS/NZ regions and sporadic E conditions observed at SWS Learmonth, 
Brisbane, Norfolk Is. and Townsville stations between 08UT-20UT. 
Normal ionospheric support for Antarctic regions. Similar conditions 
are expected for the next 3 days due to low levels of EUV ionising 
radiation (very low solar activity) offering no improvement in 
ionospheric support and mostly quiet geomagnetic activity.
