(MUFs) in the Australian region on UT day 08-Dec were near predicted 
monthly values, with some isolated periods of sporadic E impacting 
local HF propagation conditions at Darwin, Townsville, Hobart 
and Norfolk Island. MUFs are expected to be near predicted monthly 
values to 15% enhanced over 09-11 Dec, with further isolated 
periods of sporadic E possible. Shortwave fadeouts are possible.
