COMMENT: IPS SWF HF Communications Warning 46 was issued on 9 
September and is current for 9-10 Sep. Useable HF communication 
frequencies were around predicted monthly values during local 
day for Southern AUS/NZ and Equatorial regions. Notable depressed 
MUFs for Northern AUS regions during this time. Occasional disturbed 
periods for Antarctic regions over the UT day. Similar conditions 
are expected for the next 24-48 hours. Possible MUF depressions 
of 20% for Southern AUS/NZ regions and poor ionospheric support 
for Antarctic regions on 12Sep due to increased geomagnetic activity.
