COMMENT: IPS HF Communications Warning 5 was issued on 22 January 
and is current for 23 Jan only. Conditions for HF radio propagation 
were depressed for the Australian region due to an ionospheric 
storm induced by a geomagnetic storm for the UT day, 22 January. 
Expect moderate depressions to near predicted MUF values due 
to weak ionospheric storming for the UT day, 23 January. Observed 
periods of sporadic E throughout the Australian region, 22 January, 
expect this trend to continue today, 23 January.
