COMMENT: Good HF conditions observed over the last 24 hours for 
all regions with MUFs near or above predicted monthly values. 
Similar HF conditions expected 22 April. Unsettled geomagnetic 
conditions on 23-24 April may degrade HF conditions on those 
days, particularly in the Antarctic regions and S.Aus however 
MUFs are expected to remain near or marginally above predicted 
monthly values due to a winter-time ionospheric response.
