COMMENT: HF conditions were Normal with some depressions at low 
latitudes in the north due to continuing equatorial anomaly effects 
driven by neutral wind and electric field conditions. Spread 
F conditions continue during local nighttime for the most southerly 
Australasian region and are likely to continue 13-14 Aug due 
to moderate high latitude geomagnetic activity driven by elevated 
solar wind speeds from solar coronal holes.
