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 05-Oct were generally near predicted monthly 
values to 15-20% enhanced. Degraded HF conditions are possible 
over 06-07 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.
