COMMENT: SWS HF Communications Warning 5 was issued on 7 February 
and is current for 7-9 Feb. MUFs in the Australian region were 
mildly depressed during UT day 07 February. Sporadic E layers 
were observed, strong at times. For the next three UT days, 08-10 
February, mild depressions are likely in response to the predicted 
increase in the geomagnetic activity and very low levels of solar 
ionising flux.
