COMMENT: IPS HF Communications Warning 16 was issued on 7 April 
and is current for 8-9 Apr. Conditions for HF radio propagation 
on UT day 8 April were generally depressed over all Australian 
regions, except near the equatorial regions (e.g. Niue island). 
Conditions are expected to remain depressed today, 9 Apr, due 
to the aftermath of active conditions observed on UT day 7 April. 
HF conditions are expected to recover to mildly depressed to 
nearly monthly predicted values by UT day 10 April. HF users 
are advised to use lower than the monthly predicted frequencies.
