COMMENT: SWS HF Communications Warning 43 was issued on 2 October 
and is current for 2-3 Oct. Observed MUF's were strongly depressed 
over most Australian regions throughout the UT day 2 October, 
except on the day side for the equatorial Australian regions. 
These depression are the aftermaths of substorms driven by the 
very large positive polarity coronal hole. Slightly improved 
MUFs, though still near depressed levels compared to monthly 
predicted values, are expected for the next two days (3-4 October) 
as the ionosphere slowly replenishes.
