COMMENT: IPS HF Communications Warning 40 was issued on 15 December 
and is current for interval 16-18 December (SWFs) . HF conditions 
throughout the UT day were highly variable with generally weak 
ionospheric support in all Australasian regions. Ionospheric 
support recovered to near normal levels around local dawn. Persistent 
and strong sporadic E was observed in ionograms across all Australasian 
regions throughout the day. Expect current disturbed HF conditions 
to continue over the next few days but to slowly recover.
