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.
