COMMENT: ASWFC SWF HF Communications Warning 18 was issued on 
2 February and is current for 3-5 Feb. Maximum Usable Frequencies 
(MUFs) in the Australian region were near predicted monthly values 
with enhancements of 15% observed in the northern Australian 
region durling local daylight hours. Sporadic E was observed 
in the south eastern Australian region during local night hours. 
MUFs are expected to be near predicted monthly values to enhanced 
by 15% over 04-05 Feb. MUFs are expected to be near predicted 
monthly values with mild depressions possible on 06-Feb, particularly 
in the southern Australian region, due to anticipated geomagnetic 
activity on 05-06 Feb. Sporadic E is expected in the south eastern 
Australian region during local night hours. Shortwave fadeouts 
are expected.
