COMMENT: The Australasian equatorial region (PNG, Niue, northern 
Australia) has shown fairly strong depressions in MUFs today. 
Mid-latitudes slightly below average. Degradations in HF conditions 
may be expected on 23-25 Nov due to a recurrent coronal hole 
increasing geomagnetic activity and also a lack of sunspot activity 
to produce ionising flux to regenerate the ionosphere.
