COMMENT: SWS HF Communications Warning 1 was issued on 1 January 
and is current for 2 Jan only. Near monthly predicted MUFs were 
observed across Aus/NZ regions on UT day 1 Jan. Incidence of 
Sporadic E blanketing were still evident over some Australian 
ionosonde sites. The two day outlook (2 - 3 Jan) is for minor 
to moderate MUF depression in response to the recent increase 
in the geomagnetic activity associated with the coronal hole.
