COMMENT: ASWFC SWF HF Communications Warning 140 was issued on 
29 November and is current for 29 Nov to 1 Dec. Maximum usable 
frequencies (MUFs) in the Australian region on UT day 30-Nov 
were mostly near predicted monthly values to 35% enhanced. Southern 
Australian region MUFs were strongly enhanced after local dawn 
this morning. Sporadic-E was observed at Brisbane, Hobart, Townsville 
and Niue during local night hours. MUFs are now expected to be 
near predicted values to 15% enhanced as recent mild geomagnetic 
activity has declined. Mildly degraded HF conditions may be experienced 
at times during local night hours for the southern Australian 
region.
