COMMENT: IPS SWF HF Communications Warning 56 was issued on 21 
September and is current for 21-22 Sep. IPS HF Communications 
Warning 57 was issued on 21 September and is current for 22-24 
Sep. Degraded HF conditions were observed during 21 September 
over the Australian region due to low levels of ionising radiation 
and renewed elevated geomagnetic activity levels. Similar HF 
conditions are expected for the next few days. Antarctic region 
may be particularly affected by anticipated elevated geomagnetic 
activity later on day one.
