COMMENT: SWS Preliminary HF Communications Warning 52 was issued 
on 6 November and is current for 8-9 Nov. Observed MUF's were 
at predicted monthly values over the last 24 hours for Southern 
AUS/NZ and Antarctic regions, with notable depressed periods 
for Northern AUS/Equatorial regions. An expected increase in 
geomagnetic activity over 09Nov-10Nov due to coronal hole effects 
is expected to result in MUF depressions of ~20% for Northern 
AUS and Southern AUS/NZ regions, possible periods of enhanced 
MUFs for low latitude stations and disturbed ionospheric support 
for Antarctic regions over the next 3 days.
