COMMENT: SWS HF Communications Warning 2 was issued on 6 January 
and is current for 6-8 Jan. On the UT day 6 January in the Australian 
region MUFs were mostly near monthly predicted values or depressed 
by 15%. On 7-8 January more depressed MUFs are expected as a 
result of the recent increase in the geomagnetic activity, then 
the HF conditions are expected to gradually recover. HF users 
are advised to use lower than the monthly predicted frequencies.
