COMMENT: IPS HF Communications Warning 11 was issued on 1 February 
and is current for interval 1-4 February. Mostly normal HF conditions 
in the Northern Australian region with mild depressions observed 
in the South Australian and Antarctic regions, particularly the 
local day time hours. Ocassional sporadic E was also present 
in the Australian region, this trend is likely to continue. Expect 
a return to near normal HF conditions with mild depressions at 
mid to low latitudes due to lower then predicted solar activity 
for the next three days.
