20 Nov    75    Normal-fair      Near predicted monthly values/depressed 
                                 10 to 15%
21 Nov    65    Normal-fair      Depressed 10 to 15%/near predicted

                                 monthly values   

COMMENT: Maximum usable frequencies (MUFs) on UT day 19-Nov were 
mostly near predicted monthly values. MUFs are generally expected 
to be near predicted monthly values. Mild depressions are possible 
in the southern Australian region 21-Nov and 22-Nov in response 
to anticipated geomagnetic activity induced from a coronal hole 
high speed wind stream, which is yet to eventuate.
