COMMENT: Variable minor daytime depressions observed N Aus region, 
and may be experienced again today. Extended periods of disturbance 
observed Antarctic region overnight in association with geomagnetic 
activity. The Earth is now under the influence of a high speed 
coronal hole wind stream, and degraded HF conditions are expected 
S Aus/NZ/Antarctic regions next two to three days.
