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 29-Nov 
were mostly near predicted monthly values. Sporadic-E was observed 
in Niue, Canberra and Brisbane during local night hours. MUFs 
are expected to be near predicted values, with a chance of becoming 
depressed by 5-15% over 30-Nov to 02-Dec. This is due to a recent 
CME arrival, followed by possible coronal hole effects over the 
end of the period. Sporadic-E is likely to persist.
