COMMENT: IPS HF Communications Warning 48 was issued on 4 September 
and is current for 4-5 Sep. Moderately depressed ionospheric 
conditions were observed across all AUS/NZ regions during the 
last 24 hours (UT day 4 Sep). These depressions are expected 
to somewhat increase over the next two days as the result of 
active geomagnetic conditions experienced on UT day 4 Sep associated 
with coronal hole (CH 95).
