COMMENT: HF conditions were Normal with some depressions at low 
latitudes in the north due to prevailing neutral wind and electric 
field conditions in the equatorial anomaly. Expect minor depressions 
for 12 August in the Australian/Antarctic regions due to a slight 
increase in geomagnetic activity. Spread F conditions continue 
during late local nighttime early morning hours for the Hobart 
region.
