COMMENT: Degraded HF conditions were observed during the UT day, 
07 December, over the Australasian region due to low levels of 
ionising radiation and elevated geomagnetic activity. Isolated 
periods of blanketing sporadic-E conditions continue to be observed 
in Australian region. Similar HF conditions are expected for 
the next two days.
