COMMENT: ASWFC SWF HF Communications Warning 78 was issued on 
5 October and is current for 5-7 Oct. Maximum usable frequencies 
(MUFs) on UT day 06-Oct were near predicted monthly values to 
15-20% enhanced. Spread F was observed in Hobart. Degraded HF 
conditions are possible on 07 and 09 Oct due to anticipated geomagnetic 
activity from recent solar filament eruptions. MUFs are expected 
to be 10-15% above predicted monthly values on 08-Oct. Shortwave 
fadeouts are possible.
