COMMENT: The Australasian equatorial region (PNG, Niue, northern 
Australia) has again shown strong depressions overnight in MUFs, 
up to 30%. Mid-latitudes are still around average, resisting 
the expected decrease from enhanced geomagnetic activity. Degradations 
in HF conditions should be expected on 24-25 Nov due to increased 
geomagnetic activity and a lack of sunspot activity producing 
ionising flux to regenerate the ionosphere.
