COMMENT: HF conditions were Normal with some nighttime depressions
at low latitudes in the north due to prevailing neutral wind
and electric field conditions in the equatorial anomaly. Expect
similar conditions for 11 August. A high speed solar wind stream
from a coronal hole should be effective 12 Aug, causing Unsettled
geomagnetic conditions, translating to slightly more suppressed
MUFs. Spread F conditions continue during late local nighttime
early morning hours for the Hobart region.
