COMMENT: ASWFC SWF HF Communications Warning 108 was issued on 
2 November and is current for 3-5 Nov. Maximum usable frequencies 
(MUFs) were mostly near predicted monthly values to 25-50% enhanced 
in the Australian region. Scintillation was observed at Weipa 
from 03/1434-1450 UT. MUFs are expected to be near predicted 
values to 25% enhanced on 04-Nov, and on 05-Nov, until the arrival 
of an anticipated CME that was first observed on 03/0540 UT. 
MUFs are expected to be near predicted values to depressed by 
10-20% from this event and continue into 06-Nov. Isolated shortwave 
fadeouts are possible. Equatorial scintillation is possible over 
05-06 Nov.
