COMMENT: IPS SWF HF Communications Warning 13 was issued on 5 
May and is current for 6-8 May. Conditions for HF radio propagation 
were depressed up to 30% at many Australian region stations during 
the first half of 7 May UT. This may have been a weak negative 
storm effect associated with the minor (G1) storm which occurred 
on 6 May. Conditions are expected to remain near predicted monthly 
values at most locations throughout the Australian region today, 
8 May.
