COMMENT: ASWFC HF Communications Warning 92 was issued on 30 
November and is current for 1-3 Dec. Maximum usable frequencies 
(MUFs) on UT day 30-Nov were depressed by up tpo 25% in the Australian 
region. Significant amounts of sporadic E were observed across 
the Australian region on 30-Nov. MUFs are generally expected 
to be mildly depressed over 1-2 Dec and near monthly predicted 
values to mildly depressed on 3-Dec. Degraded HF conditions may 
be experienced during local night hours on 1-3 Dec for the southern 
Australian region due to mildly enhanced geomagnetic conditions 
induced by coronal hole wind streams.
