2. FORECAST (08 NOVEMBER - 10 NOVEMBER)
Date   T index  Conditions       MUFs                              
08 Nov     5    Normal-fair      Depressed 15%/near predicted 
                                 monthly values
09 Nov    -5    Normal-fair      15 to 20% below predicted monthly 
                                 values

                                 values   

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, with some 
notable depressed periods for Northern AUS/Equatorial regions. 
Possible increase in geomagnetic activity in the latter half 
of the UT day for 08Nov may result in periods of enhanced MUFs 
for low latitude stations and depressed ionospheric support for 
mid to high latitudes. Continued 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 and disturbed 
ionospheric support for Antarctic regions.
