08 Oct   130    Normal-fair      Depressed 5 to 15%/near predicted 
                                 monthly values
09 Oct   145    Normal           Near to 15% above predicted 
                                 monthly values

                                 monthly values   

COMMENT: Maximum usable frequencies (MUFs) on UT day 07-Oct in 
the Australian region were near predicted monthly values. with 
depressions of up to 35% observed in the southern Australian 
region. Spread F was observed at Hobart during local night. Ionospheric 
scintillation was observed at Darwin at 07/1248UT. MUFs are expected 
to be near predicted monthly values to 15% depressed on 08-Oct, 
with depressions mostly likely in the southern Australian region, 
due to recent geomagnetic activity. MUFs are expected to be near 
predicted monthly values to 15% enhanced on 09-10 Oct as geomagnetic 
activity eases. Shortwave fadeouts are possible.
