COMMENT: ASWFC SWF HF Communications Warning 134 was issued on 
16 November and is current for 16-17 Nov. Maximum usable frequencies 
(MUFs) on UT day 16-Nov in the Australian region were mostly 
near predicted monthly values to 15% depressed, with the most 
depressed conditions occurring during local night hours. Spread 
F was observed at Hobart and sporadic E was observed at multiple 
sites in the Australian region. Nighttime sporadic E is expected 
to be common in the coming weeks. MUFs are expected to be mostly 
near predicted monthly values to 10-15% on 17-18 Nov due to ongoing 
coronal hole activity. MUFs are expected to be near predicted 
monthly values on 19-Nov.
