COMMENT: IPS HF Communications Warning 4 was issued on 21 January 
and is current for 22 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, 21 January. 
Expect moderate depressions to near predicted MUF values as the 
ionospheric storm subsides for the UT day, 22 January. Observed 
periods of sporadic E throughout the Australian region, 21 January, 
expect this trend to continue today, 22 January.
