COMMENT: Maximum usable frequencies (MUFs) were mostly near predicted 
monthly values to 15% enhanced in the Australian region. MUFs 
are expected to be near predicted monthly values to 15% enhanced 
over 3-4 Nov. There is a chance of mild depressions in the southern 
Australian region on 5-Nov due to geomagnetic activity. MUFs 
are expected to be near predicted monthly values to 15% enhanced 
in the northern Australian region. Isolated minor shortwave fadeouts 
are possible.
