COMMENT: Maximum usable frequencies (MUFs) on UT day 15-Nov in 
the Australian region were mostly near predicted values. Sporadic-E 
was common at most Australian sites during local night hours. 
Nighttime sporadic-E is expected to be common in the coming weeks. 
MUFs are expected to be mostly near predicted values but may 
become depressed by 10-15% due to coronal hole activity.
